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.
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.
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.
How do we liquefy gases?
Maybe
What is oxygens temperature?
Oxygen can be almost any temperature.
What happens to oxygen at 183 degree Celsius?
That is the boiling point of oxygen. So if the temperature in going downwards then oxygen will begin to liquefy whereas if the temperature is rising, then liquid oxygen will begin to boil.
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.
How do you use the word Liquefy in a sentence?
You can liquefy metal by heating it to a high enough temperature.
What are true statements about both nitrogen and oxygen?
they are both made of protons, neutrons, and electrons
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 the temperature required to liquefy a gas?
Depends which gas
What is the importance of pressure?
It liquefy the gas at its critical temperature
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.
What must be done to oxygen and hydrogen to change them liquids?
If you mean the individual gases you will need to apply pressure and or reduce the temperature to liquefy the gases. If you mean by forming a compound react them together. The end product is water which is liquid at room temperature and pressure.

How does oxygen affect the earth and weathering?
By that it splits rocks and makes the oxygen go through it. When the temperature changes, the oxygen spreads into the rock and it cracks open.
