What is the difference? I read that thermal energy includes both kinetic and potential energy but isn't that what internal energy is?
Cheers!

In thermodynamics , thermal energy refers to the internal energy present in a system due to only to its temperature.TT0 said:What is the difference? I read that thermal energy includes both kinetic and potential energy but isn't that what internal energy is?
Thermal energy is the kinetic energy of molecules in a substance due to its temperature, while internal energy is the total energy of all molecules in a substance, including both kinetic and potential energy.
Yes, thermal energy can be converted into internal energy through processes such as conduction, convection, and radiation.
Thermal energy is a component of internal energy, and the two are directly proportional to each other. An increase in thermal energy leads to an increase in internal energy.
Yes, there is a limit to the amount of thermal and internal energy a substance can have. This limit is known as the absolute zero, which is the lowest possible temperature where all molecular motion stops and there is no thermal or internal energy.
The transfer of thermal energy from one substance to another can increase or decrease the internal energy of a substance, depending on the direction of the transfer. For example, when a cold object is placed in contact with a warm object, heat transfer occurs from the warm object to the cold object, increasing the internal energy of the cold object.
