equations of thermodynamics that occurs in the lesson

Answer:

First Law of Thermodynamics:Euniv = Esys + Esurr = 0 

Esys = q + w
 

w = - PV

The sign convention for this equation reflects the fact that the internal energy of the system decreases when the system does work on its surroundings.

Esys = q (if and only if w = 0)
 
Hsys = Esys + PV
 
H = E + PV
