  1. A.Temperature is a measure of the average kinetic energy of the molecules of a substance
  2. B.Heat is a measure of the total kinetic energy of the molecules in a system
  3. C.Different materials require different amounts of heat to cause a given change in temperature
  4. D.all of the above
  5. E.A and B only.
Show the answer and explanation

Answer: D (all of the above)
