This means that heat energy cannot be created or destroyed.The First Law says that the internal energy of a system has to be equal to the work that is being done on the system, plus or minus the heat that flows in or out of the system and any other work that is done on the system, said Saibal Mitra, a professor of physics at Missouri State University.
