State and prove first law of thermodynamics

WebFirst Law of Thermodynamics (VW, S & B: 2.6) There exists for every system a property called energy. E = internal energy (arising from molecular motion - primarily a function of temperature) + kinetic energy + potential energy + chemical energy. Defines a useful property called "energy". WebThe first law of thermodynamics states that the total energy of an isolated system is constant. Energy can be transformed from one form to another, but can neither be created …
