What is the difference in size between a pond and a lake?
A lake's water is deeper than six feet, so no plants can grow at the bottom of the deepest parts. So, you can have a really large pond or a really small lake. It all depends on depth, which also influences temperature. Ponds are more stable; lakes will layer (or stratify). The plants influence dissolved oxygen, which varies in ponds and is more stable in lakes.

What direction do underground springs flow?
Underground springs typically flow in the direction of least resistance, following natural slopes and geologic structures like faults and fractures. The flow can be influenced by factors such as topography, rock porosity, and water pressure.
What is the difference between 45 rpm and 33 rpm Vinyls?
The 45 RPM records or vinyls sound as they were intended to sound when played at 45 revolutions per minute (at the 45 setting on a record player) while the 33 RPM records sound right at the 33 revolutions per minute speed. Then, there is the issue of size. Records that are 33 RPM are larger in diameter than 45's. Also 33's can hold more songs than 45's do. Usually, 45's have only one song on a side and were used as demo records for radio stations (yes, radio stations used to play music on records before they went to tapes and now to digital music on computers) and for releasing "singles" so that people could listen to a new band without having to pay for a whole album. 45 RPM records or vinyls are recorded at 45 revolutions per minute and are consequently played back at the same speed to achieve exact replication of the original recording. Subsequently, 33 1/3 RPMs are recorded at that speed, and played back at that speed to hear the audio as it was recorded. Generally 45s are recorded on smaller 7" disks, whereas 33 1/3s are recorded on larger, full sized 12" disks. This is not always the case, as some 12" records are recorded at 45 RPM for higher, or audiophile, sound quality.
What is the notion of time in different religious traditions?
From a Christian standpoint: The law of time was created by God. We do not know how his existence relates to time because we cannot comprehend not having a beginning. He is able to see into the future but has not predestined each individual's life because he has allowed us to choose our own actions. So where as his purposes will always be realized, we all have our own choice on whether to be part of those purposes. (Compare Isaiah 55:11, Ecclesiastes 9:11 and Deuteronomy 11:26-28)
How are mouthwashes different from gargles?
Not a lot at all. Most mouthwashes can be used as gargles as most have a disinfectant or antibacterial solution, But some gargles are medicated and meant just to be gargled and not to be used as a mouthwash. I would say that Listerine would be both a mouthwash and a gargle, but Hydrogen peroxide (H2O2) would be a gargle only.
What is the difference between acidaemia and acidosis?
Both terms refer to the level of acidity (as measured by pH) being higher than normal (i.e., the pH was lower than normal. Low pH is more acidic.). Acidosis is typically used to refer to the low pH number,b while acidemia relates to the process that produced the low pH number. - Mark R. Bower
Vap·o·ri·za·tion
n.
The act or process of vaporizing, or the state of being converted into vapor; the artificial formation of vapor; specifically, the conversion of water into steam, as in a steam boiler. or changing states from liquid to a gas.
This is different from evaporation. Evaporation is only at the surface of the water, while vaporization is all the way throughout.
Vaporization takes place when the particles in a liquid gain enough energy to move independently, forming a gas.
Specialization and Division of labor?
Division of labour is the breaking down of production process into seperate stages so that each process is peformed by group of workers.Specialisation is the concentration of productive effort of an individual or group of individual to one particular economic activity
Calculate the weight of a solid object?
If the object is made of only a pure element or a pure compound whose density you could look up, you could multiply the density of the substance by the volume of the object, then, assuming you are on or near Earth's surface, multiply the product by 9.8 m/s^2.
What is the time difference between Mexico and Australia?
It depends on the cities involved, as both Mexico and Australia lie within three different time zones:
Mexico:
Australia:
This means time differences can be as little as 14 hours or as big as 18 hours.
What is the difference between a life settlement and a viatical?

What are the differences between gas and steam?
Steam is the gaseous form of water, but it really can only be considered to be fully gaseous when it is in a dry state, as at temperatures below the dry saturated steam line, it will contain droplets of water. Thus at atmospheric pressure it needs to be above 100 celsius to be dry, the required temperature for dryness rises with pressure. The Critical point for steam is at 374 celsius and 220 bar pressure, above this temperature it is supercritical and cannot be liquefied by any further increase in pressure. Thus in summary, steam above the boiling point at a particular pressure behaves as a gas, and above 374 celsius it is a gas whatever the pressure.
Most gases like oxygen and nitrogen have liquid phases at much lower temperatures, ie well below any normal atmospheric condition experienced even in extreme low weather conditions, so we regard them as always gaseous, but actually they also have liquid/gaseous interface conditions, we just don't experience them in practice except in very low temperature work.
In popular terminology 'steam' is what you see rising above the surface of hot water or from the spout of a kettle, but the fact that it is visible is due to the presence of water droplets and in this condition it is not gaseous steam as described above.
What are the difference between the lagrange equation and lagrange function?
The lagrange function, commonly denoted L is the lagrangian of a system. Usually it is the kinetic energy - potential energy (in the case of a particle in a conservative potential).
The lagrange equation is the equation that converts a given lagrangian into a system of equations of motion. It is d/dt(\partial L/\partial qdot)-\partial L/\partial q.
Is there a difference between a diamond and cubiczirconia?
a diamond is nature made from immense pressure over a very long time. A cubic zirconia is man made of a white crystalline substance to look like a diamond. A real diamond will cut glass. The latter will not.
What are the Differences between the mass and width?
Mass is a measure of the amount of matter in an object, while width is a measure of how broad or wide something is. Mass is typically measured in grams or kilograms, while width is measured in units such as meters or centimeters.
What is the difference between frequency and wavelength?
Wavelength is the distance between peaks of a sinusoidal wave.
It is denoted by a λ, and is measured in metres.
The frequency is the time is takes for this to take place. It is denoted by an 'f' and it is measured in Hertz (Hz).
They are linked by the equation frequency x wavelength = speed of light (around 300,000km/s).
What is the difference between black gram and green gram?
Green gram and Black gram are both the species of pulses very related to each other, but these can be differentiated very easily. Black gram differs from green gram by having short seeds, hairy pods, and oblonged seeds. Seed colur vary from blackish to oily colour Black gram is very nutritious so its prize is very high in India and other countries. (MUBASHIR IQBAL)

What is the difference between a hydrogen bomb and an atomic bomb?
Atom bombs work by the principle of atomic fission (splitting large atomic nuclei), while hydrogen bombs work by atomic fusion (combining small atomic nuclei). The hydrogen bomb is hundreds or thousands of times more powerful than the atom bomb. The hydrogen bomb uses an atom bomb as a trigger.
The term "atomic bomb" is a general term that can be applied to any nuclear weapon. What kind of weapons are there and where does the hydrogen bomb fit in?
There are fission devices (the "regular" atomic bomb), fission-fusion devices (the clean hydrogen bomb) and fission-fusion-fission devices (the dirty hydrogen bomb).
In the atomic bomb (fission device), uranium or plutonium is forced into a "critical mass", causing the atoms of the element to fission or "split" into the smaller atoms of other elements. When they split, they give off neutrons that split even more of the atoms (i.e. chain reaction). Each atom gives off a tremendous amount of energy as a tiny fraction of its matter is converted.
In the clean hydrogen bomb (fission-fusion device), the heat given off by a fission explosion is directed at a container of fusible hydrogen (deuterium and/or tritium). The heat and pressure causes the hydrogen to fuse into helium, the same process that takes place in the Sun and stars. This reaction produces an incredible amount of energy, because again a tiny amount of matter from each atom is converted.
In the dirty hydrogen bomb (fission-fusion-fission device), the energetic neutrons from the fusion explosion are so numerous that a casing of "ordinary" uranium (mostly U-238) will also fission, creating a fantastic amount of energy (up to 90% of the total yield of the bomb can be from this fission). Thicker casings or additional stages could theoretically create massive bombs 1000 times the power of fission bombs. The largest bomb ever tested, the 50-megaton "Tsar Bomba" of the Soviet Union, was built with this design (three stage design: fission primary, fusion secondary, fusion tertiary). If it had used actual uranium around the third stage, it could have yielded 100 megatons or more. However, the fallout from such a bomb would be large and widespread, risking contamination of areas far beyond the target. In the configuration tested, the "Tsar Bomba" was actually the cleanest nuclear bomb ever detonated (in terms of amount of fallout per kiloton of yield), even though it produced more total fallout than any other nuclear bomb ever detonated (because of the very high yield).
The design used by modern weapons was created by the physicists Edward Teller and Stanislaw Ulam in 1951.
The "Hydrogen" bomb refers to the "Fusion" of a Hydrogen Isotope on an Atomic scale by way of steps of multiple reactions thus yielding a much more powerful explosion upwards of 500 Million Tons of TNT. It is also known as "ThermoNuclear". The "Atom" or "A" bomb refers to the "Fission" or "Fusion" of Uranium or Plutonium in a single step reaction, rather than multiple steps,yielding an explosion.
What is Difference Between HPLC UV detector Spectrophotometer uv detector?
HPLC UV detector is a component used in high-performance liquid chromatography (HPLC) to monitor eluent absorbance, while a spectrophotometer UV detector is a standalone instrument used to measure the absorption of light at different wavelengths. HPLC UV detectors are specifically tailored for chromatography applications, whereas spectrophotometer UV detectors are more versatile and used for various analytical purposes.
The term hard and soft acid is a qualitative one which refers to the polarizability of the acid (and typically refers only to Lewis acids). A soft acid is one that is highly polarizable, whereas a hard acid is one that is not polarizable.
For more information, and a list of many examples of hard and soft acids, see the Web Links to the left.
Yes!
Answer 2
No, not really. X-rays are basically gamma rays. Because of this, you
normally need something dense to stop them, like a lead sheet. If there
were better shielding properties, we wouldn't need lead aprons for
hospital employees. It may, however show up on an x-ray film as an
object. Although carbon paper may absorb some of the radiation, it's not
enough to act as a shield.
An experiment may be beneficial. Duplicating (as closely as possible) the x-ray energy from the source (dental x-ray machine, etc.) and then seeing the effects of carbon paper on the normal results (images, etc.) when used as the blocking property in the x-ray beam.
Whats the difference between brazing and soldering?
"Nothing really. It concerns the metal your working with. You braze with brass, solder with lead and weld with steel. That's about it.
In general, brazing refers to higher temperature processes than soldering does, but the line is pretty fuzzy."
I don't think its as simple as that, I thought the processes were distinguished by their temperature ranges for a while too until I was told otherwise. There are high temperature solders and low temperature brazing materials. ARC wielding is the actual metallurgical bonding of similar materials together, as opposed to soldering which I feel is more of a semi-physical bond. Long story short I don't know the exact difference from a mettalurgical standpoint but they are infact much different in that respect.
There is no fundamental difference between brazing and soldering; it is primarily historic. The word "braze" is derived from an old English word "braes" meaning to cover with brass. While "solder" is derived from an old french word "soudure" which means to make solid. Based on the historic developments, brazing process is defined as one where the filler melts above 450 C while soldering is where the filler melts below 450 C. But beyond that technically there is no difference.
Natural features are significant land or water that is not man-made. By definition, natural is existing in or produced by nature; not produced by man or artificial.
Geologically, a formation is a natural body of earth, such as an outcrop or deposit with distinctive and characteristic properties allowing study and mapping of the structure or strata on or below the surface.
A feature is typically defined as related to archaeology and consists of man-made or altered items that are not portable and must otherwise be recorded. For the purposes of this section the archaeological component of 'feature' is ignored and redefined as an easier way of describing formations not so apparent to the typical definition.
Relative intensity refers to the level of effort or exertion required to perform an activity, relative to an individual's maximum capacity. It is often used in exercise science to prescribe and monitor the intensity of workouts based on a percentage of an individual's maximum effort. Understanding relative intensity helps tailor training programs to achieve specific fitness goals.
