Clouds
A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes up to several miles above sea level. They are generally produced by the condensation of water vapor. Other clouds, less commonly seen, are composed of smokes or dusts.

What causes mold to form below the water line in the toilet bowl?
Maybe you have a rare fungus infection in side your body that comes out in your urine, the urine ways more then the water so it goes to the sides and bottoms bellow the water line and will stick to the side growing molds if not propery cleaned
How do you find the low pressure side from a window unit air condition?
Hi: The low pressure side is the biggest line going to or fro the compressor. It will always connect directly to the cooling coil. Be careful, as that the lines can contain quiet a bit of pressure and expecially if you tap into the wrong one at the wrong time while unit is running. At any rate,,,, you didn't ask but how to identify the low pressure line and now you have your answer. Hope this is usefull to you. Jimiwane
Well it is quitet simple,there is a water cycle. When the rain comes down it falls into rivers, then it goes into the ocean.One day it may get very hot, the average when rain evaporates is 72 deegrees, they have descovered scientificaly that the water gets so hot it turns into steam. Then after that it forms a cloud. I am sure you knew this but then the cloud gets to heavy to carry its self any more and it rains;the same thing happens over and over.Thats how rain evaporates.

Is the stopper in front of the sweeper?
Yes, the stopper stops/delays an attack forming in the middle third. The sweeper prevents the ball from entering the middle part of the field in the defensive third. See definition at www.soccerhelp.com.
What is mixed together to form a drink called an Arnold Palmer?
An Arnold Palmer consists of half lemonade and half ice tea. If you put the lemonade in before the ice tea, the ice tea floats on top of the lemonade.
What is the difference between force and pressure?
A force is a push or a pull which changes how fast an object moves. Pressure is the force on an object divided by the area over which the force is spread. A force will change the velocity of an object. This means it will start it moving if it is still, stop it moving, speed it up, slow it down or change its direction! Pressure takes into account the area over which the force is acting. A force spread over a big area will give a low pressure. The same force spread over a small area will give a high pressure. For an excellent account of force and pressure see the links below. You might think of force as a 'vector' and pressure as a 'scalar'. A vector must include direction as a parameter as well as magnitude; and a scalar has magnitude without dependence on direction. Force on an object when the force is not balanced by other forces will compel an object to move. An object sitting motionless at one atmosphere of pressure will not be compelled to move simply because of the presence of the pressure alone. Pressure is the force over an area applied to an object in a direction perpendicular to the surface. Force is a push or pull that can cause an object with mass to accelerate. Force has both magnitude and direction. p = F / A, where:
p is the pressure,
F is the normal force,
A is the area.
What is the right pressure of freon in low?
The proper pressure of freon in the low side of an air conditioning system typically ranges from 25-45 psi, depending on the specific system and operating conditions. It is important to refer to the manufacturer's specifications for the correct pressure levels for your particular system. If in doubt, it is always recommended to consult a professional HVAC technician.
Why does hot air hold more water vapour than cold air?
Because the molecules in the hot air are more spread out, allowing water to easily form within the gaps of the molecules.
Cold air is more dense and does not allow water to form easily between the molecules.
Is moist air heavier or lighter than dry air?
Moist air is heavier than dry air, because of the water.
Why is hot air lighter than cold air?
Because its density is lower. At constant pressure, a given volume of hot air thus weighs less than the same volume containing colder air. ---------------------------------------- remark: This can be easily seen from the equation for ideal gases p*V = n*R*T, with p: pressure V: volume n: number of particles within the given volume R: ideal gas constant T: Temperature
Can a gas change direcly into liquid?
Almost al gasses can change to liquids bij cooling or putting it under preasure.
Yes gas can change into liquid and liquid can change into gas. A gas is a substance that has no definite volume or independent shape that that tends to expand indefinitely. Gases are compressible. A liquid is a substance that flows freely and has a definite volume but has no independent shape. Liquids are slightly compressible. Change of state is the process that occurs when enough heat is added or removed to change a substance from one physical state to another.
Sure, it's called condensation. It'll happen if you cool the gas.
If a 5050 mixture of cyclohexane-toluene is boiled what will the relative ratios of the vapor be?
Determine the bp of clycohexane and that of toluene. The lower bp chemical will come off first. A simple distillation rig will provide a means of monitoring when the first chemical has been removed. The remaining chemical will likely have some amount of the first remaining, depending upon distillation rig used.
The more complicated answer is that the ratios of vapor will change over time as the solution boils.
When the solution is boiling the total vapor pressure of the solution is equal to atmospheric pressure. That total vapor pressure is the sum of the two partial pressures of toluene and cyclohexane (the components). So what your asking is what is the partial pressure of each; then you can compare them to make a ratio. Well, the partial pressure of each component in the vapor is the vapor pressure of that component at the current temperature of the system times the mole fraction of that component in the liquid.
Toluene has a lower vapor pressure than cyclohexane (it is less volatile) so if you start with a 50/50 mixture of cyclohexane and toluene (50/50 by mole fraction, that is, but 50/50 by volume is pretty close), the partial pressure of toluene is (lower number)x50% and the partial pressure of cyclohexane is (higher number)x50%, so there's more cyclohexane in the vapor than there is toluene. However...
Those vapors tend to float away and leave the system. Since there's initially more cyclohexane in the vapor, more cyclohexane is leaving the system and you no longer have a 50/50 mixture. Eventually it gets to the point where the partial pressure of toluene is (lower number)x(larger fraction) and the partial pressure of cyclohexane is (higher number)x(smaller fraction) so there is actually more toluene in the vapor.
What is turbulence and what causes it?
The most common manifestation of turbulence occurs when aircraft fly through areas of unstable air, which may contain updrafts, downdrafts, and wind shear.
However, the word "turbulence" can be applied to any fluid motion, where a smooth flow is twisted into eddies and irregular paths. It means that all particles in the system do not follow the same path, that the velocity profile for particles is different. The "Reynolds number" is used to predict the amount of turbulence.
Turbulence is usually caused by an increase in temperature and/or an increase in flow rate. Another cause for turbulence is surface roughness. The rough texture of the surface will "trip" or cause a laminar flow to become turbulent. On aircraft this increases the drag of the surface; e.g. the wing. This is one reason sail planes are very smooth, the laminar flow has less drag so the aircraft glides farther. On the other hand, there are times when you want a turbulent flow on the surface of the wing because it gives the boundary layer more energy to keep it attached, and thereby prevent or delay stalling of the wing at higher angles of attack. An example of this is seen on commercial airliners, you'll sometimes see a row of small "plates" attached to the wing or horizontal tail surface; these introduce turbulence to ensure the flow does not separate.

What are liquids and gases known as D?
Hard to be sure without more context, but "D" generally refers to deuterium, which is an isotope of hydrogen. Deuterium is simply hydrogen with an extra neutron (for a total of one proton and one neutron in the nucleus). Common molecules include D2 and D2O, although any molecule that contains hydrogen can also be found with D instead.
What does evaporation rate mean?
Speed it up!
The evaporation rate is the factor determining how fast or slow a liquid evaporates, this depends on the temperature the surface area of the liquid, the strength of air currents above the liquid, pressure above the surface of the liquid or the nature of the liquid.
-Qwasas
Evaporation Rate is how much of a factor(such as heat,humidity,or wind) affect the "rate" of evaporation.
The old saying "Two cooks in one kitchen never works" is so true! It's your mother's home and she likes things where they are for a reason. It could be as simple as she enjoys where she has put something like a chair, vase, etc., or, it's easier for her to get too. It is not your home! If she asks you to do something such as cook and you don't do things exactly as she would do it then yes, it's nagging and you should say, "Look, you asked me to cook and I'm doing it the way I know how and if you don't appreciate it then feel free to do the cooking yourself." The older people get the more habits they incur. They have set routines because it makes them feel comfortable. For a daughter or son living at home it could be upsetting for them. My sister-in-law's two sons moved out into their own basement suite. While mom meant well by bringing in bags of groceries she also took it upon herself to move the sugar bowl, spice rack and salt and pepper shakers and her sons complained because they couldn't find them! LOL Mom had every right to help out, but did not have the right to move anything the way the boys had placed things. The only suggestion I can give you is leave furniture, vases, etc., alone and leave it where your mother has placed them. This is her right. If she complains when she asks you to do something then it's time to sit down and communicate without yelling or fighting over it. The both of you should be able to come to some common ground.
Which temperature scale is not directly or indirectly based on a phase changes in water?
Fahrenheit Scale is the temperature scale that is not directly or indirectly based on the phase changes in water. Another similar temperature scale is Celsius Scale.
Why do liquids tend to form spherical droplets?
Liquids tend to form spherical droplets due to surface tension, which causes the molecules on the surface of the droplet to minimize their surface area. This shape is energetically favorable because it reduces the overall surface area, minimizing the energy required to maintain the droplet's integrity. Spheres have the smallest surface area for a given volume, making them the most stable shape for liquid droplets.
This could indicate an issue with your heater core or thermostat. The heater core may be clogged or the thermostat may be stuck open, causing the inconsistent heating and quick cooling. It's recommended to have a mechanic inspect and potentially replace these components if needed.
Why would a 1989 Toyota Cresida not shift when cold but do fine after warm up?
This issue could be due to low transmission fluid levels or fluid that is too old and needs to be changed. The cold temperature may be thickening the fluid, causing it to have difficulty flowing properly until it warms up. It's recommended to check the transmission fluid level and condition first.
When the wind doubles does the pressure in the sails increase 8 times?
When the apparent wind speed is doubled, the pressure on the sail is quadrupled. That is because the pressure on the sail (or the side of your house or a billboard sign) is proportional to the square of the speed of the wind. If the wind speed triples, then the pressure goes up by a factor of nine, because three squared is nine.
follow the compressor lines...and everyone should have a manual for their vehicle, and a professional shop manual should be available at the library in the reference section--you can make copies of the necessary information...good luck :)
Pressure in air conditioner in a 1996 Buick Skylark is high why?
most likely cause is that it has non-condensables in it, probably water vapor from a leak on the low side
next most likely is that the condensor (radiator) is clogged up with bugs or else the fan isn't working
next would be that someone has put an alternate refrigerant in it
Where is the low pressure air conditioning fitting located on a 1997 grand am?
It's usually near the receiver/dryer. That's the silver thing that looks like a tomato juice can with the ends rounded. Sometimes the receiver/dryer is wrapped, sometimes not. In any case, there should be a fitting that has a screw on dust cap. The 134A refrigerant for your vehicle comes with many options. You can get oil charge, UV Dye, colored dye, seal conditioner and generic-refrigerant-only. Unless you know of a specific need for any of the other options, just get the generic. Some of the cans even have a fitting and a gauge on them for convenience. Just be careful that you don't over-fill, otherwise you'll blow the seals out of the compressor, then you'll need a new compressor.
