The first law of thermodynamics is simply the general law of conservation. We know that internal energy of U of a system can change through two modes either heat or work. This equation is the first law of thermodynamics dQ = dU + dW .

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.
