WebThe first law of thermodynamics relates the change in internal energy dU to the work dW done by a system and the heat dQ added to it. By definition, in an adiabatic process, the heat exchanged dQ = 0. Substituting this in the first law and rearranging gives. The second term is easy: the work done dW when a system changes its volume V by dV is PdV.
