What causes internal energy to increase? When a closed system receives energy as heat, this energy increases the internal energy. It is distributed between microscopic kinetic and microscopic potential energies. A second kind of mechanism of change in the internal energy of a closed system changed is in its doing of work on its surroundings. […]
