The first law of thermodynamics is simply the case of – (1) Charles law (2) Newton's law of cooling (3) The law of heat exchange (4) The law of conservation of energy
(4) The law of conservation of energy Explanation: The first law of thennodynamics is a version of the law of conservation of energy for thermodynamic systems. It states That the change in the internal energy of a system is equal to the heat added to the system plus the work done on the system.
