Explanation:
Detailed explanation-1: -With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature.
Detailed explanation-2: -Heating a substance makes its atoms and molecules move faster. This happens whether the substance is a solid, a liquid, or a gas.
