Which type of energy makes up most of the internal energy of a solid substance?

A. Kinetic energy from translation

B. Kinetic energy from rotation

C. Kinetic energy from vibration

D. Potential energy from intermolecular forces

The correct answer option is C. Kinetic energy from vibration.

Explanation:

The energy of the random motion of the particles of an object is referred to as the internal energy of that object (substance). So the type of energy that makes up most of the internal energy of a solid substance is kinetic energy from vibration.

Internal energy is related to the temperature. When heat is supplied to an object, the molecules vibrate and energy of these molecules increases.
