Homework Help: Change of enthalpy

  1. Aug 17, 2005 #1
    as Q(heat transfer)=P*dV + dE
    Q is a non state function,
    while the change of enthalpy,
    dH=P*dv+dE,
    i suppose it is equal to the Q above but why dH is a state function while Q is not since they are the same?

    The enthalpy, H, is a state function. Is that necessarily true of change of enthalpy?

    so u mean dH is not a state function?
