Atoms can be split through a process called nuclear fission, in which the nucleus of an atom is split into two or more smaller nuclei. This process releases a large amount of energy in the form of heat and radiation. Nuclear power plants use controlled nuclear fission reactions to generate electricity.

Define the sub levels of elements?
Sublevels of elements refer to the energy levels within an atom where electrons are found. These sublevels are designated by the letters s, p, d, and f. Each sublevel has a maximum number of electrons it can hold (2 for s, 6 for p, 10 for d, and 14 for f) and they are arranged in order of increasing energy within an atom.
What is exhaust method in dyeing?
In dyeing, the exhaust method refers to the process of adding dye to a textile substrate until all the dye has been absorbed by the substrate or bath. This method is useful for achieving full color coverage and intense color saturation on the fabric. The exhaustion of dye in the bath indicates that the dye has been fully utilized in the dyeing process.
Federal standards for city-supplied drinking water are governed by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act, which sets limits on various contaminants. Commercial bottled water, regulated by the Food and Drug Administration (FDA), must meet the same quality and safety standards as tap water but is subject to different testing and monitoring requirements. Additionally, bottled water may be subject to labeling regulations that differ from those for tap water.
What is the current price of dimethyl ether?
I do not have real-time data on the current price of dimethyl ether. Prices can vary based on location, supplier, and market conditions. It is recommended to check with local suppliers or online marketplaces for the most up-to-date pricing information.
An eductor is a device that uses a fluid (usually a liquid or gas) to create a vacuum or achieve a pumping action. It works based on the principle of fluid dynamics, where a high-velocity fluid stream entrains a lower-velocity fluid or solid material through a nozzle, generating a suction effect. Eductors are commonly used for tasks like mixing liquids, evacuating gases, and transporting solids in various industries.
What happend on a German ship with hydrogen?
The German passenger airship Hindenburg, filled with hydrogen gas, caught fire and was destroyed while attempting to land in Lakehurst, New Jersey in 1937. The disaster resulted in the death of 36 people and marked the end of the era of hydrogen-filled airships for commercial air travel.
Great question. The answer is almost certainly not. Gasoline is only 3/4 the density of fresh water. You could not float in it. As an addendum, by "staying afloat" the question implies effort as in treading, as one would tread water. Yes. But, because the viscosity of Gasoline is less than water it would take greater effort, more stamina and this causes heavier breathing. Beside the fact that gasoline is absorbed thru the skin and blisters, if help were not immediately forthcommiing, the noxious fumes would soon render one unconcious and thus result in drowning.
What powder in bullets can cauterize wounds?
Answer:Gunpowder.
Answer:
Unless you are an actor in a Rambo movie don't count on this working. There are a lot of very good quick clot powders (e.g. QuikClot) available that stop all manner of blood loss form nasty wounds and hurt a lot as they do it too.
Gunpowder (black powder) is not a common propellant in modern bullets. Most use nitrocellulose or other similar chemicals. In a deep wound these could casue a lot of gas overpressure in the wound which would undo the good the cauterizing fixes.
Under the ASTM Method D 323 (Reid vapour pressure), it is the absolute vapour pressure exerted by a liquid at 100°F. The higher this value, the more volatile the sample and the more readily it will evaporate. Unlike distillation data, vapour pressure provides a single value that reflects the combined effect of the individual vapour pressure of the different petroleum fractions in accordance with their mole ratios. It is thus possible for two wholly different products to exhibit the same vapour pressure at the same temperature - provided the cumulative pressures exerted by the fractions are the same. A narrow-cut distillate, for example, may exhibit the same vapour pressure as that of a dumbbell blend, where the effect of heavy fractions is counterbalanced by that of the lighter ones. In conjunction with other volatility data. Reid vapour pressure plays a role in the prediction of gasoline performance.
What approximate temperature will a rubber floor mat melt?
Rubber floor mats typically melt at temperatures around 250-300 degrees Fahrenheit. It is important to check the specific material and manufacturer guidelines for accurate temperature thresholds to prevent damage.
At what temperature saturated steam turns into superheated steam?
all temperatures above saturated steam is super heated steam.
"Superheated" steam isn't so much a scientific term as a technical term. Steam is more efficient the more energy it has (the molecules have more kenetic energy/are hotter).
During the height of steam locomotive development, the most fuel efficient way to accomplish this was to collect the steam, and then run it through a series of loops that are exposed to the exhaust gases of the original combustion, there-by further heating the steam.
Because the steam receives no further moisture, but received further heat energy, it is considered 'dry' steam. Superheat was a term coined by the engine builders as a way to promote the design as a way to sell their engines.
Because the superheater pipes carried steam pressure, they added additional equipment that had to be inspected as per ICC regulations. Because they also were exposed to the exhaust gas stream, they had a likelyhood of being erroded by the waste fuel being exhausted as well as the 1300+ degree combustion exhsut gasses.
Why is petroleum jelly used in the hanging-drop procedure?
Petroleum jelly is used in the hang drop procedure because , it reduces the evaporation of the drops of fuild . ----------------------
ALSO, this type of sealing material is used primarily to not only reduce evaporation of liquid but to eliminate air current in the preparation as well.
It is made of specially cohesive material on one side, and other non-stick material on the other side, giving tape its ability to stick. However, all of the cohesive products are not released to the public, since they are mostly secret.
What are the Advantages of liquid level measurement?
Some advantages of liquid level measurement include real-time monitoring, improved process control, early detection of leaks or spills, and increased safety by preventing overfilling or underfilling of tanks.
To find the final temperature, we can use the ideal gas law. First, calculate the initial specific volume of the mixture using the quality of the saturated steam. Then, use the equation of state to find the final specific volume at the new pressure. Finally, determine the final temperature using the final specific volume and the new pressure.
Can you use LEL meter used for checking hydrocarbon for checking hydrogen gas LEL?
No, a Lower Explosive Limit (LEL) meter that is designed for detecting hydrocarbons may not accurately measure hydrogen gas LEL. Hydrogen has a different LEL concentration compared to hydrocarbons, so using a meter specific to hydrogen gas is recommended for accurate results and safety in potential hazardous environments.
What is an electrolyte used for?
electrolysis is a scientific word. It means to split the water into two terms of chemistry. which H2O into H2+O. H equals to hydregen, and O equals to Oxygen. In GIN(Global Issues ?), a lot of scientists are interested in electrolysis. Because, if you eletrolysis the water, Hydregen appears out. So the hydregen can be the engine of the car, which uses the CO2, and breaks the environments down. That is what the GIN is learning about. And also, hydregen doesn't break the environment down, so that is keeping the environment green, and friendley.
What is acrylic plastic made from?
Acrylic plastic is typically made from methyl methacrylate monomer, which is a liquid compound derived from natural gas and petroleum. It can be produced through a process called polymerization, where the monomer molecules are chemically bonded together to form long chains, creating the acrylic plastic material.
What is wet corrosion and galvanic corrosion?
The dry corrosion is the corrosion of the metal that takes place in the absence of conducting(aqueous) medium. The reaction between metal and oxygen (atmosphere) at elevated temperatures in perfectly dry conditions is an example of dry corrosion.
The most abundant gas in the Earth's atmosphere is nitrogen, making up about 78% of the air we breathe. Nitrogen is essential for living organisms to build proteins and DNA. It is also used in various industrial processes, such as in the production of fertilizers and as a protective gas in food packaging.
Where can non oil based plastic be acquired?
The materials used to make plastic could come from coal, wood / plant oils or bio mass. They could be produced by fermenting sugar from crops and using the alcohol as a starting material (feedstock)for the production of the raw materials.
As far as I know nobody makes such plastics commercially yet, but someone else might know more......
Try googling " bioplastics " for more information
