Which of the following describes the idea that heat is transferred as thermal energy by the interaction of moving particles?

a. kinetic energy

b. the theory of thermal equilibrium

c. the kinetic theory of heat

d. thermal energy

Correct Answer is "C" (The Kinetic Theory Of Heat). I took a quiz and got it wrong :(

C. the kinetic theory of heat

Explanation: The heat is transferred from the object at higher temperature to the one at lower temperature by the motion of the particles.

The temperature determines the thermal energy of an object, higher the temperature, more is the vibration of the particles. Heat is the energy which is transferred from one object to another. When placed in contact, the energy is transferred from hotter to colder object.

The particles of the hotter object  vibrate with greater energy and transfer heat from one to another till the thermal equilibrium is reached. The correct theory describing this is the kinetic theory of heat.
