Casey Hunt · Answer 1

The average amount of motion of atoms and molecules of a substance measured by:

D. Temperature

Explanation:

The molecules of a substance are always in motion. The motion is due to the energy present in them. The energy present in these molecules is the kinetic energy. This kinetic energy is measured by calculating the total heat energy of the substance. More the heat energy greater is the molecular motion. Since heat can be measured by measuring the temperature. Measuring the temperature of a body will give the idea of amount of heat present in the body. Thus, on measuring the temperature we can measure the average amount of motion in atoms and molecules of a substance.
