How does increasing the pressure on an object affect the density of the object?
Increasing the pressure on an material (especially for liquids or gases) decreases the volume of the object and thus increases its density via the atomic number density . Compressibility (also known as the coefficient of compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.

How is nitrogen gas produced?
Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption ). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk delivered nitrogen. Commercial nitrogen is often a byproduct of air-processing for industrial concentration of oxygen for steelmaking and other purposes. When supplied compressed in cylinders it is often called OFN (oxygen-free nitrogen). Commercial-grade nitrogen already contains at most 20 ppm oxygen, and specially purified grades containing at most 2 ppm oxygen and 10 ppm argon are also available.
What is the name of the mixture of nitric and hydrochloric acids?
The mixture of nitric and hydrochloric acids was known as aqua regia (royal water), celebrated for its ability to dissolve gold, the king of metals. The discovery of nitrogen is attributed to the Scottish physician Daniel Rutherford in 1772, who called it noxious air.
Why do we use nitrogen in aircraft fuel?
In some aircraft fuel systems to reduce fire hazard (see inerting system ). To inflate race car and aircraft tires, reducing the problems of inconsistent expansion and contraction caused by moisture and oxygen in natural air. Nitrogen is commonly used during sample preparation in chemical analysis.

The nitrogen cycle describes movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere.
How much energy does each degree of freedom have?
Each degree of freedom has an energy of half kT, for the translation this adds up to 3/2 kT.
How many elements melt slightly above room temperature?
There are four elements that melts slightly above the room temperature.
What temperature does chocolate melt?
Chocolate melts at about 97°F (3 6°C), which is just below body temperature. Chocolate feels good to eat because it melts in your mouth! The temperature in a room is usually around 65°F (18°C). A material with a melting point lower than this will be a liquid.
What is the root mean square speed of a molecule?
From the kinetic theory of gases the root mean square speed of a molecule is the square root of 3*kT/m, where k is the boltzman constant, T is the temperature in Kelvin and m is the molecular mass.
Is nitrogen faster than air?
The nitrogen molecules would be, on average, a bit faster because they are lighter than the average air molecule (but not much faster because N2 is very close to the average since air is most N2, O2 has a similar molecular weight, and Argon is such a small fraction).
Is there a reason to be concerned with the maximum speed of molecules in a gas sample?
As far as I know, there is no reason to be concerned with the maximum speed of molecules in a gas sample. The properties of the gas would be determined by the bulk of the molecules moving at speeds near the RMS.
