The answer to the question “It is also called heat” is thermal energy.

Explanation

In thermodynamics, the term "heat" specifically refers to the transfer of thermal energy from one system to another due to a temperature difference. Thermal energy is the total internal kinetic and potential energy of the microscopic constituents of a system, which is mainly due to their motion and positions. Unlike other forms of energy, such as chemical or potential energy, thermal energy is directly related to the temperature of the substance.

When heat energy is added to a substance, it can increase the temperature, cause a phase change, or do both, depending on the context. Unlike potential energy, which is stored energy based on position or configuration, or kinetic energy, which relates to the motion of objects, thermal energy is specifically concerned with the energy associated with the random motion of particles at a molecular level, making it the correct answer in this context.
