WebAnswer (1 of 5): The internal energy of a system can be changed by interacting with its surroundings in such a way that heat or work is added or taken out of the system, as well … WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side equals the total mechanical energy.
