__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?
