Question

Why thy volume of gas increase when temperature increase

Answer 1

When the temperature of a gas increases, the molecules within the gas gain energy and move faster. This increased molecular motion results in more frequent and forceful collisions between gas molecules and the walls of the container. These collisions create more pressure on the walls of the container, causing the volume of the gas to expand. In other words, as the temperature increases, the gas molecules move faster and push against the walls of the container with more force, leading to an increase in volume.
