As a subject matter expert in the field of thermodynamics, I can provide a comprehensive explanation of the relationship between thermal energy and heat.
Thermal energy and heat are often used interchangeably in everyday language, but in the context of physics and thermodynamics, they are distinct concepts.
Thermal energy refers to the total internal energy of a system due to the random motion of its molecules. This includes kinetic energy from the movement of the molecules and potential energy from the forces between them. It is a state function, meaning it depends only on the current state of the system and not on how the system reached that state.
On the other hand, heat is a form of energy transfer that occurs between two systems or objects due to a temperature difference. It is not a property of the system itself but rather a process that involves the transfer of energy from one place to another. Heat always flows from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached.
The key difference between the two is that thermal energy is a measure of the energy contained within a system, while heat is the energy that is transferred between systems. When we say that two objects are in thermal equilibrium, it means that there is no net transfer of heat between them because their temperatures are the same. However, this does not imply that they have the same amount of thermal energy. For example, a small cup of hot coffee and a large bathtub of lukewarm water might be at the same temperature, but the bathtub has more thermal energy due to its greater mass and volume.
The statement that 'Thermal' energy and 'Heat' energy mean the same thing is not accurate. While they are related in that both involve the energy associated with the temperature of a system, they are not synonymous. 'Internal' energy, which includes thermal energy, is a broader term that encompasses all the energy stored within a system, including the energy from molecular motion, chemical bonds, and nuclear forces. Thermal energy is a component of internal energy that specifically relates to the temperature of the system.
In summary, while thermal energy and heat are related, they are not the same. Thermal energy is a measure of the energy within a system due to the random motion of its molecules, and it is a state function. Heat, however, is the energy that is transferred between systems due to a temperature difference and is a process, not a state function.

When two objects are at the same temperature, there will be no transfer of thermal energy, and we say they are in Thermal Equilibrium. 'Thermal' energy and 'Heat' energy mean the same thing. 'Internal' energy and 'Thermal' energy do not mean the same thing, but they are related.Apr 24, 2016
