WebIn other words, the temperature of a system increases if and only if there is an increase in the average kinetic energy of its particles. Two gases, such as H 2 and O 2, at the same temperature, therefore must have the same average kinetic energy. This can be represented by the following equation. WebIf the same gas is shown at different temperatures, curve IV coresponds to the highest temperature. If different gases are shown at the same temperature, the average kinetic energy of gas lis less than that of If different gases are shown at the same temperature, molecules of gas I must weigh less than molecules gas II.
