In other words, when you add heat to a closed system, the total energy will stay the same. But, when you remove heat from a closed system, the total energy will decrease until it reaches zero.
WebThe first and the most simple formulation is for the closed system, where there is no material exchange with surroundings. In energy balance equation for the closed system, the energy change of the system is described as the energy change of internal energy, potential energy and the kinetic energy.
