उत्तर
A gas's molecules are in a state of constant random motion. They possess kinetic energy. When a gas is heated, the average kinetic energy per molecule of the gas increases. As a result, its temperature rises (the average kinetic energy per molecule being proportional to the absolute temperature of the gas).
