SUMMARY

The discussion clarifies the distinction between heat transfer (Q) and change in enthalpy (dH). Q is identified as a non-state function, while dH is confirmed as a state function, despite their mathematical similarities in the equations Q = P*dV + dE and dH = P*dv + dE. The key takeaway is that while both expressions involve similar terms, the properties of state functions dictate that dH is independent of the path taken, unlike Q.

PREREQUISITES
  • Understanding of thermodynamic concepts, specifically state functions

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?
