What else can I help you with?
Which gas can be liquefied under pressure at ordinary temperature?
Carbon dioxide (CO2) can be liquefied under pressure at ordinary temperature.
What is the critical temparature?
The temperature at which all the physical states of matter are coexists is called critical temperature. The temperature above that the gas can not be liquefied is called critical temperature of that gas.Gases with high critical temperature are liquefied easily.
Can gas become liquefied?
Yes - low temperature and/or high pressure are needed, how extreme of either depends on the gas.
How does ammonia gas liquefied?
Ammonia gas is liquefied by subjecting it to high pressure and low temperature. This process compresses the gas molecules together, reducing their kinetic energy and causing them to condense into a liquid state. This liquid ammonia is used in several industrial applications, such as refrigeration and fertilizer production.
A gas can be liquefied by?
increasing pressure and decreasing temperature, following the principles of the gas laws. By reducing the volume and cooling the gas, it will condense into a liquid state.
Can a gas be liquefied?
lowering the temperature
Will all the real gas be liquefied at high pressure?
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.
How does petroleum gas get liquefied?
By freezing it - lowering the temperature - usually done by putting it under pressure
How does petroleum gas liquefied?
By freezing it - lowering the temperature - usually done by putting it under pressure
How ammonia gas liquefied?
Liquefaction by cooling down (lower temperature) and compression (higher pressure)
What refers to the temperature above which a gas cannot be liquefied by an increase in pressure?
This is known as the "Critical Temperature". For example, CO2 has a critical temp of 31.2 degrees C and NH3 has a critical temp of 132 degrees C
Why hydrogen gas is liquefied first than helium gas?
Hydrogen gas is liquefied first than helium gas because hydrogen has a higher critical temperature and pressure than helium. This means that hydrogen can be liquefied at higher temperatures and pressures compared to helium. Helium requires lower temperatures and pressures to be liquefied, making it more challenging to achieve compared to hydrogen.
