Answer 2

Answer:

Internal energy is the energy associated with the random, disordered motion of molecules.

For example, a room temperature glass of water sitting on a table has no apparent energy, either potential or kinetic. But on the microscopic scale it is a seething mass of high speed molecules traveling at hundreds of meters per second.

The unit of energy in the International System of Units (SI) is the joule (J).
