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

When the temperature of a gas increases does the volume of the gas increase in a rigid steel container?
No, because the gas is in a rigid steel container, its volume cannot increase as the temperature increases (assuming the steel does not deform). Instead, the pressure of the gas inside the container will increase. Of course, if the pressure is high enough, the container will explode, lowering the pressure and causing the gas to expand.
What is the volume occupied by 26.9g of argon gas at a pressure of 1.23 and a temperature of 374?
The question cannot be answered because there are no units given for the pressure not temperature.
What happens when air is heated in a bottle?
if it's plastic or aluminum or glass and it's sealed it will explode because the air tries to escape. if the top is not on the air will escape easily,If it's in a plastic bottle the sides of the bottle gets pushed in
Does water change into gas if atmospheric pressure is increased?
no it cannot but if the temperature is slightly increased over 6 C it will evaporate at a slow rate.
What are the differences between gas and steam?
Steam is the gaseous form of water, but it really can only be considered to be fully gaseous when it is in a dry state, as at temperatures below the dry saturated steam line, it will contain droplets of water. Thus at atmospheric pressure it needs to be above 100 celsius to be dry, the required temperature for dryness rises with pressure. The Critical point for steam is at 374 celsius and 220 bar pressure, above this temperature it is supercritical and cannot be liquefied by any further increase in pressure. Thus in summary, steam above the boiling point at a particular pressure behaves as a gas, and above 374 celsius it is a gas whatever the pressure. Most gases like oxygen and nitrogen have liquid phases at much lower temperatures, ie well below any normal atmospheric condition experienced even in extreme low weather conditions, so we regard them as always gaseous, but actually they also have liquid/gaseous interface conditions, we just don't experience them in practice except in very low temperature work. In popular terminology 'steam' is what you see rising above the surface of hot water or from the spout of a kettle, but the fact that it is visible is due to the presence of water droplets and in this condition it is not gaseous steam as described above.
Which gases cannot be liquefied by increasing their pressure?
Nig, its because the pressure is what makes the gas, if there ain't no pressure, ain't no gas.
gas?
has no definite volume or shape.
What cannot be melted?
This question is dependent on pressure. Many things that cannot ordinarily be melted, can be liquefied if there is sufficient pressure applied. Water does not melt if the pressure is low enough. Some things that do not ordinarily have a liquid state are:carbon dioxideIodinemethaneammonium

If the volume of a gas increases what happens to the temperature?
According to Charles' Law: Volume of a gas increases as temperature inceases. But if the gas is contained in a rigid container then the volumme cannot increase, but the pressure will.
Where is valve located to increase water pressure?
There is no such thing as a valve cannot increase or decrease pressure IT can throttle volume or stop the flow.=One would need a pressure booster pump to increase pressure=
How to calculate mass with volume temperature and pressure?
You cannot. If you know the volume, temperature and pressure of a pencil, you will be no closer to knowing its mass!
What is the volume occupied by 26.9g of argon gas at a pressure of 1.23 and a temperature of 374?
The question cannot be answered because there are no units given for the pressure not temperature.
What would cause the pressure of the gas to increase?
The answer to this question lies in the ideal gas law: PV=nrT in which: P = presssure V = Volume n = number of moles r = ideal gas constant T = temperature because we want P to increase, we can achieve that in a couple of ways: 1. decrease the volume 2. increase the number of moles 3. increase the temperature. Value of r cannot change; it is a constant.
Is pressure after throttling is more or less?
You cannot increase steam pressure through a valve without adding heat to it. Throttling steam always reduces its pressure.
Why does the pressure of a gas increase as its temperature increases?
Pressure is defined as the force and number of collisions the particles of gas have with the walls of its container. Temperature is defined as the average kinetic energy of particles of matter. What this means is that when you raise the temperature of a gas, you are raising the average kinetic energy of the particles by providing a source of heat. Because the particles have more kinetic energy, they move faster and more forcefully. Then the particles have more collisions with the container with more force--the definition of pressure.
Is thulium a solid a liquid or gas?
This cannot be answered without the temperature and pressure having been provided. At Standard Temperature and Pressure thulium is a solid. It melts at 1545 °C and boils at 1950 °C at standard pressure (101.325 kPa).
