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.

Do you freeze gas to make it a liquid?
most gases only become liquid under extreme pressure, not cold.Additional answerThere's a critical temperature, which is different for each gas, above which it won't liquefy even if compressed. Certainly a domestic freezer won't be nearly cold enough for most gases. But carbon dioxide will solidify with no compression at all.

Is it possible to liquefy c02 at a temperature of 40 degrees celsius?
The critical temperature for carbon dioxide is 304K (87.8°F [31°C]). That means that no amount of pressure applied to a sample of carbon dioxide gas at or above 304K (87.8°F [31°C]) will cause the gas to liquefy. At or below that temperature, however, the gas can be liquefied provided sufficient pressure is applied. The corresponding critical pressure for carbon dioxide at 304K (87.8°F [31°C]) is 72.9 atmospheres (~73000 kPa). In other words, the application of a pressure of 72.9 atmospheres of pressure on a sample of carbon dioxide gas at 304K (87.8°F [31°C]) will cause the gas to liquefy.

What is the difference between LNG and LPG?
LNG is liquefied natural gas, while LPG is liquefied petroleum gas.LNG is mostly methane which is temporarily cooled in order to liquefy the gas. LNG must be refigerated to a cryogenic temperature of about -162C (-260F) in order to liquefy the gas and stays at or slightly above atmospheric pressure. LNG must be refrigerated because room temperature is above the critical point of methane, meaning no liquid can be condensed at this temperature (no matter what the pressure is).LPG is a mixture of propane and butane (in no specific proportion) which is stored in a pressurized container and is stored at room temperature. Butane and propane have a higher critical point, and therefore pressurization is sufficient to liquefy the fuel.
