Heat energy of an object is

  • A.The average energy of the molecules of the object
  • B.The total energy of the molecules of the object
  • C.The average velocity of the molecules of the object
  • D.The average potential energy of the molecules of the object

Answer: B

Heat energy is the total energy of the molecules of the object.

It depends on how many molecules there are as well as how energetic each is, so a bucket of warm water holds more heat than a cup of boiling water. Temperature, by contrast, measures the average molecular kinetic energy.
