The boiling point. The process is condensation, but condensation and boiling occur at the same temperature since the boiling point represents the temperature at which gas and liquid are in equilibrium with each other.
What else can I help you with?
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 importance of pressure?
It liquefy the gas at its critical temperature
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.
Why can ammonia gas be easily liquefiied and helium can not?
Ammonia gas can be easily liquefied due to its relatively low critical temperature and pressure. In contrast, helium has a critical temperature and pressure that are very close to absolute zero, making it difficult to liquefy at standard temperatures and pressures.
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.
Is ammonia solid at room temperature?
No. Ammonia is a gas at room temperature..
What is the temperature required to liquefy a gas?
Depends which gas
Melting point of Ammonia?
Ammonia does not have a melting point since it exists as a gas at standard temperature and pressure. Ammonia will liquefy at temperatures below -33.34 degrees Celsius under pressure.
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.
Will methane liquefy under pressure?
Yes, methane can liquefy under pressure. At standard atmospheric pressure, methane remains a gas at room temperature, but when subjected to high pressures and low temperatures, it can transition into a liquid state. Specifically, methane liquefies at around -161.5°C (-258.7°F) at atmospheric pressure, and increasing the pressure can further facilitate this process. This property is utilized in various industrial applications, including the storage and transportation of natural gas.
What is the importance of critical pressure?
Critical pressure is important because it is the pressure at which a substance transitions between liquid and gas phases at its critical temperature. It represents the maximum pressure at which a substance can exist as a liquid, and is crucial for understanding phase behavior and designing processes such as distillation and extraction. Critical pressure is also used to define the critical point of a substance on a phase diagram.
