If the volume of the container is not fixed, increasing the temperature will cause a gas to expand (increase the volume), and contract when cooled (decreasing the volume). This would be the case for a gas inside a piston, or inside a rubber balloon.

If the volume is fixed, then increasing the temperature will increase the pressure, and decreasing the temperature will decrease the pressure. This would be the case for a gas in a closed solid container, like a canister or sealed metal box.

Increasing pressure will cause the gas to contract (reducing the volume), and decreasing the pressure will cause the gas to expand (increasing the volume). Again, this is if the volume is not fixed. If the volume is fixed, then increasing the pressure will increase the temperature, and decreasing the pressure will decrease the temperature.

These concepts are all determined by something called the Ideal Gas Law. To find out more about how this works, see the Related Questions links below this answer.

Gases can also be changed to a liquid or solid if the temperature is too low or the pressure is too high. As an example steam changes to a liquid when it touches a cold object, and nitrogen gas can be converted to liquid nitrogen by compressing it to very high pressures.

What is the effect of temperature change on the pressure of a contained gas?

A decrease in temperature will cause the gas molecules to lose kinetic energy and slow down, resulting in a decrease in pressure. Conversely, an increase in temperature will cause the gas molecules to gain kinetic energy and move faster, leading to an increase in pressure. This relationship is described by the ideal gas law.


Joule Thomson effect is temperature dependent or not?

The Joule-Thomson effect is temperature dependent. It describes the change in temperature of a gas as it expands or is compressed without doing external work. If the gas undergoes adiabatic expansion (no heat exchange with surroundings), its temperature will change depending on its initial temperature, pressure, and the nature of the gas.


How could a student test the effect of removing heat from a gas that is stored in a sealed container?

The student could measure the temperature and pressure of the gas in the sealed container before and after removing heat. By tracking changes in temperature and pressure, the student can observe how cooling the gas affects its properties, such as volume and pressure. This can help demonstrate the relationship between temperature, pressure, and volume in a gas.


What is the effect on pressure when the temperature of a gas at constant volume is increased?

Universal Gas Law: P*V/T = a constant, where P = gas pressure [Pa], V = volume [m3], and T = gas temperature [K]. Therefore, when the gas temperature increases, the pressure increases linearly with it, when the volume is constant.


Does changing the temperature of a gas has no effect on the volume of the gas?

No, it does affect the volume of a gas according to the ideal gas law (PV=nRT).

When the pressure on a liquid or gas goes up their temperature goes up or down?

When the pressure on a gas goes up, the temperature of the gas also goes up. This relationship is described by the ideal gas law. For liquids, the effect of pressure on temperature is less direct and can vary depending on the specific properties of the liquid.

What is the effect of varying the temperature on the volume of a constant mass of a gas at a constant pressure?

the relation is given by charles law which says that the volume of a constant mass of gas at constant pressure is directly proportional to the temperature so increase in temperature causes an increASE in the volume
