Question

Temperature of a substance is proportional to the average kinetic energy of the motion of the molecules of that substance.

Answer 1

True, according to the Kinetic Molecular Theory.

Answer 2

The correct choice is

True

According to kinetic molecular theory, average kinetic energy per molecule of a gas is directly proportional to the temperature. The average kinetic energy is given as

KE = 1.5 k T

where T = temperature  , k = Boltzmann constant

hence

temperature is proportional to the average kinetic energy
