Exploring Thermal Energy and Heat Transfer Concepts

What is the primary difference between thermal energy and heat?

• Thermal energy is the transfer of heat between objects.

• Heat is the transfer of thermal energy due to a temperature difference.

• Heat is the measure of the kinetic energy of particles.

• Thermal energy and heat are the same concepts.
