Question

what is internal energy prove that it is a state function and how its correlated with enthalpy​

Answer 1

Answer:

The change in the internal energy of a system is the sum of the heat transferred and the work done. At constant pressure, heat flow (q) and internal energy (U) are related to the system's enthalpy (H). The heat flow is equal to the change in the internal energy of the system plus the PV work done
