Webb4 mars 2024 · The First Law of Thermodynamics is a fundamental principle of physics that applies to all types of closed systems, including gases, liquids, and solids. It is an essential concept in the study of thermodynamics and is used to understand and predict the behavior of various physical systems. 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. WebbThermodynamics Use of the First Law of Thermodynamics in Isothermal process The process in which temperature of a system remains constant but pressure and volume change it is called isothermal process.
