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