Question

What happens to a gas's thermal energy as that gas's temperature increases?

Answer 1

here is your answer

The average kinetic energy of a gasparticle is directly proportional to thetemperature. An increase intemperature increases the speed in which the gas molecules move. All gases at a given temperature have the same average kinetic energy. Lightergas molecules move faster than heavier molecules


hope you understand

Answer 2

Decreasing Pressure. The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.
