Crystallines can liquefy under pressure if it is sufficiently high. Generally the opposite happens where they become more dense and compressed as the pressure increases.
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.
Liquefy it by cooling and reducing pressure and then do fractional distillation.
solubility means the quantityof a solute that will liquefy in a particular solvent under certain conditions
No. It takes a combination of pressure and temperature to liquefy some gases. Hydrogen and helium were the last gases to be liquefied and that was with pressure and extremely low temperature.
Helium
It will stay as air. To liquefy it, it has to be pressurised, allowed to cool, then made very cold by de-pressurising it. So being cols will liquefy it. Pressure will not, at any achievable pressure.
The critical pressure of a substance is the pressure required to liquefy a gas at its critical temperature. Some examples are shown below.
It liquefy the gas at its critical temperature
To pack more gas into the container it is required to liquefy under pressure
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.
The inner core of the Earth, which is composed of metal rather than rock, does remains solid because it is under immense pressure.
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.
Liquefy it by cooling and reducing pressure and then do fractional distillation.

All forms of gas will liquefy at a sufficiently low temperature.
