    where U 0 denotes the internal energy of the combined system, and U 1 and U 2 denote the internal energies of the respective separated systems. Adapted for thermodynamics, this law is an expression of the principle of conservation of energy, which states that energy can be transformed (changed from one form to another), but cannot be created or ...
