The density of a substance equals its mass divided by volume. If the volume decreases (such as by compressing a gas), its density will increase.
Gas can be compressed so much that it turns into a liquid form.
Compressed elemental gas (as in Hydrogen, Oxygen, etc) will however not remain in this state when pressure is released. It will simly turn back into gas again.
Some gasses that are a mix of various components may even change structure due to high pressure and temperature. Some gasses can be turned into plastic. Commonly done with natural gas from "oil" wells.
Density= mass/volume
if the volume is decreased, the density will decrease as well.
Also consider the Ideal Gas Law:
PV=nRT
P = pressure
V = volume
n = number of moles of gas
R = gas constant (Google that, it depends on the actual raw data)
T = temperature
When you compress the gas, n, R, and T stay the same. When you increase the pressure, the volume must decrease (a gas law) so the volume must decrease in order to balance out the equation and maintain equilibrium.
tl;dr? answer is YES :)
Air density changes as more air is put into a limited space. It gets higher.
No, compression does not affect the number of moles.
the change in volume affects the density of solids, liquids , and gases by when the volume of a liquid , solid . or gas expands the density changes.
no it's a gas, compressed to around 1% of normal volume. If it was compressed to the liquid state, you'd call it liquified natural gas (LNG).
... its volume is constrained only by volume, temperature and pressure. Pressure and temperature can both go up if volume is decreased. ... its volume is established by kinetic energy, rather than interatomic bonds.
compressed gas
The gas pressure in a closed container increases with volume and increased temperature. Likewise, the pressure will decrease with decreased temperature.
When a gas is compressed, so volume is decreased, the pressure increases. P=1/V
Yes It does increase. http://webbook.nist.gov/chemistry/fluid/ While this website doesn't include chlorine, any gas that is compressed will increase in density. Different gasses all have different compression-density relationships, but all gasses that are compressed will increase in density.
There will be the same amount of gas but in a smaller space. Density is mass/volume So as volume decreases and mass is constant, the density increases.
Depends on the density of the gas.
The increase in pressure signifies the increase in the number of collisions of the gas atoms with its container, this can result from 2 factors (when temperature is constant): either there is gas added, or the volume of the container has been decreased. Thus the Density, which is mass (which can be equated to amount of gas) divided by volume, and increase in mass or decrease in volume will effectively increase the density of the gas.
As pressure increases, the molecules of the gas are compressed, reducing the amount of space between molecules, which results in a decreased volume.
The atoms or molecules of a gas will increase in thermal energy when the gas is compressed. The kinetic energy of those atoms or molecules will increase as they are forced closer together in compression, and the temperature of the gas will increase.
Although volume and pressure are held constant, some of the gas escapes from the bottom of the balloon, thus decreasing the mass of the gas in the balloon. If mass is decreased, then density is also decreased because density=mass/volume. Such a decrease in density of the balloon causes it rise.
CNG is compressed natural gas
A gas has a lower density than either a liquid or solid because its molecules are not as compressed as the other two states of matter. Gas has weaker intermolecular bonds than either a solid or liquid.

It will increase. Density is mass/volume. Mass remains constant since no matter is entering or escaping. Lowering the temperature decreases the volume. Same mass in a smaller space= increased density.
