An indicator of average kinetic energy is temperature. Temperature is directly proportional to Kinetic energy of the molecules of an element.
Answer:
Temperature
Explanation:
The energy contained by a body due its motion is known as kinetic energy.From kinetic theory of gases, the average kinetic energy is proportional to temperature. More the temperature, more would be the speed of the particles. Gases having same temperature would have same average kinetic energy.
Thus, an indicator of average kinetic energy is temperature.
