Question

Write 2-3 sentences explaining what happens when you change the temperature of a gas.

Answer 1

When the temperature of a gas increases, the kinetic energy of its particles also increases, causing them to move more rapidly and collide more forcefully with the walls of their container. This results in an increase in pressure if the volume is kept constant, or an expansion of the gas if allowed to expand. Conversely, decreasing the temperature reduces the kinetic energy and can lead to a decrease in pressure or contraction of the gas.
