A. Heat
B. Temperature
C. Internal energy
D. None of these
Check Answer
The correct answer is B) Temperature.
The average kinetic energy of the molecules of a body is directly proportional to the temperature of the body. Temperature is a measure of the average kinetic energy of the particles in a substance, and the higher the temperature, the greater the average kinetic energy of the molecules. Heat and internal energy are related to temperature, but are not determined solely by the average kinetic energy of the molecules. Heat is the transfer of energy from one body to another due to a difference in temperature, while internal energy is the sum of the kinetic and potential energies of the molecules in a substance.
