The molecules of the gas will stop moving.
it settles down
It has no more kinetic energy
This gas is hydrogen.
Helium
At the standard temperature and pressure, hydrogen gas has the lowest density.
It turns into gas
If you compress a gas the temperature increases
The pressure of a gas increases with an increase in temperature.
The pressure of a gas increases with an increase in temperature.
Once pressure reaches vapor pressure, gas will liquify at that temperature.
The temperature decreases
The solubility of gas increases as the temperature decreases.
