Webb12 jan. 2024 · In physics class, we write the first law of thermodynamics as d U = d Q − d W and in the physical chemistry class, we write the same law as d U = d Q + d W. The reason being the sign convention is different in both the cases. In physics we take work done by the system as positive and in chemistry work done on the system. Webb24 feb. 2024 · The first law of thermodynamics is a restatement of the law of conservation of energy. It states that energy cannot be created or destroyed in an isolated system; energy can only be transferred or changed from one form to another.
