WebThere's the isometric process, also known as isochoric or isovolumetric, where the change in volume is 0, which meant, remember, that means no work can be done. The work was also 0 for an isometric process. And then there's the adiabatic process where no heat is allowed to flow into or out of the system. WebA further implication of the energy equation is possible if a new property is introduced. Since p is constant, pdv is identical with d(pv) Thus the energy equation can be written as Q d u pv Q d pv du w w But specific enthalpy h = u+pv i.e. ∂Q = dh or in the integrated form Q = h 2-h 1 or for mass m, of a fluid
