what is the difference between enthalpy and latent heat? are they both same?

Enthalpy and latent heat are simply related. The latent heat of va- porization Lv is defined as the difference in enthalpy between a fixed mass of vapor and the same mass of liquid. That is Lv=Hvap−Hliq . Similarly, the latent heat of fusion is given by Lf=Hliq−Hsol , and the latent heat of sublimations is given by Ls=Hvap−Hsol . These enthalpy differences are related through Ls=Lf+Lv
