WebThe first law cannot indicate whether a metallic bar of uniform temperature can spontaneously become warmer at one end and cooler at others. All that the law can state is that there will always be energy balance if the process occurs. It is the second law of thermodynamics that provides the criterion for the feasibility of any process.

WebThe equation for the first law of thermodynamics is given as; Δ U = q + W where, Δ U = change in the internal energy of the system. q = the algebraic sum of heat transfer between system and surroundings. W = work interaction of the system with its surroundings. First law of thermodynamics for isochoric process The work done is given by d W = P d v. WebFirst law of thermodynamics, that states that energy can neither be created nor destroyed, it can only change from one form to another.
