Question 21

Structure of Matter and Kinetic Theory

The absolute temperature of a perfect gas is proportional to the average

  1. A.potential energy of the molecules
  2. B.separation between the molecules
  3. C.kinetic energy of the molecules
  4. D.velocity of the molecules.
Show the answer and explanation

Answer: C (kinetic energy of the molecules)

Explanation

Kinetic theory shows that the kelvin temperature of an ideal gas is proportional to the average kinetic energy of its molecules.
