If allowed to do work on the surroundings, the temperature will decrease as the pressure decreases.

If expanded against a vacuum or adiabatically, most gases will get colder. At room temperature, all gases except hydrogen, helium, and neon cool upon expansion by the Joule-Thomson process; these three gases experience the same effect but only at lower temperatures; when starting at room those three gases will actually WARM when expanded across a valve.

Assuming all other variables stay the same, the pressure will decrease by a proportional amount.

If you quickly reduce the pressure of a gas, its temperature will usually decrease. Of course, it won't always remain colder - it can heat up again over time.

What will happen if the Gas is kept at low temperature and high pressure?

At low temperature and high pressure, the VOLUME of the gas will be reduced.


What happen to the pressure of a gas if the volume of the gas is tripled of a constant temperature?

The pressure is reduced to one third of the original pressure. The pressure will stay the same you are only changing the volume


What will happen to the pressure of gas in a container if the temperature is increased?

The gas is likely to expand and raise the pressure inside the can. Should the pressure become too great the can will burst.


What will happen if a gas is held at constant temperature has an increase in pressure applied to it?

The volume of the gas will decrease. the gas will also attempt to increase in temperature.


What would happen if fluorine and neon came together?

Under standard conditions of temperature and pressure, nothing.However under conditions of unusually high temperature and pressure a metastable compound neon fluoride can form.
