The correct answer is Kinetic energy form.

Key Points

  • When heat energy is supplied to a substance, it causes the molecules of the substance to move faster.
  • This increase in the kinetic energy of the molecules results in an increase in the temperature of the substance.
  • The temperature of a substance is a measure of the average kinetic energy of its molecules.
  • As the temperature of a substance increases, the molecules move faster and collide with each other more frequently.
  • These collisions transfer energy from one molecule to another, and the overall kinetic energy of the substance increases.
  • Therefore, the supplied heat energy is stored in the form of kinetic energy of the molecules of the substance.
