It has got to do with the size of the atoms and their weight.
Gases are simple molecules with weak forces between molecules
All the particles move around with a certain amount of energy. This energy is what we often count as heat.
When we reduce the temperature of a gas, the particles move slower and slower, and get closer together until they start to touch at which point the gas will start to condense
This can further be helped by pressure.

Which gas is most difficult to liquefy?
Helium
Is it true that above the temperature no amount of pressure will casue a gas to liquefy?
The critical temperature of a gas is the temperature at or above which no amount of pressure, however great, will cause the gas to liquefy.
What happens to the volume of an object when temperature decrease?
According to Charles law, the volume of gas decreases with lower temperatures and increases with higher temperatures
Is displacement of liquid by liquid easier than by gas?
Yes, Liquid -Liquid displacement is easier than displacement with gas. the liquids cannot be compressible, but gas can. the volume of gas required for displacement is lower than volume of liquid.
What intermolecular forces is most important in allowing Xe gas to liquefy?
Ion-dipole
Why do low temperatures and high pressures required to liquefy chlorine gas?
Chlorine molecules have weak intermolecular forces of attraction.
How can you liquefy a gas?
All forms of gas will liquefy at a sufficiently low temperature.
Can you liquefy a gas?
All forms of gas will liquefy at a sufficiently low temperature.
What do you have to do to a gas to get a liquid?
Cool the gas sufficiently and it will liquefy.
What is the temperature required to liquefy a gas?
Depends which gas
Which gas is most difficult to liquefy?

Is it true that above the temperature no amount of pressure will casue a gas to liquefy?
The critical temperature of a gas is the temperature at or above which no amount of pressure, however great, will cause the gas to liquefy.
What is helium's natural state of matter?
Helium is usually in the form of a gas. Helium can liquefy, but it does so at a lower temperature than any other substance.
Why must gas shipped in the winter to the Northern states different from the gas shipped in the summer to the southern states?
Gasoline best burns when it is vaporized. Longer chain hydrocarbons, or less branched dhain hydrocarbons have a lower vapor pressure. These burn easier at higher temperatures than at cooler temperatures.
What is the importance of pressure?
It liquefy the gas at its critical temperature
What temperature does gas freeze at?
That is impossible to answer. It depends on which gas you are talking about and its pressure. At standard atmospheric pressure, oxygen freezes at -218.8 degrees C. Of course, under most circumstances the gas will liquefy before it freezes.
What is the importance of critical pressure?
The critical pressure of a substance is the pressure required to liquefy a gas at its critical temperature. Some examples are shown below.
