Item EG046003: When the average speed of molecules increases, the thermal energy of an object increases.

How is the average speed of the molecules of an object related to the thermal energy of the object?

  1. When the average speed of the molecules increases, the thermal energy of the object increases.
  2. When the average speed of the molecules increases, the thermal energy of the object decreases.
  3. The relationship between the average speed of the molecules and the thermal energy of the object depends on whether the object is a solid, a liquid, or a gas.
  4. The average speed of the molecules is not related to the thermal energy of the object.
