The variation of internal energy with temperature at constant pressure
zhlédnutí 2,1KPřed 3 lety
This video describes the variation of internal energy with temperature at constant pressure. The expansion coefficient and isothermal compressibility of substances is used to establish universal relationships between the heat capacities at constant pressure and volume. There is an error in the definition of isothermal compressibility at 8:50. Kappa_T=-1/V(dV/dP)_T rather than -1/V(dV/dT)_P. Tha...

    Thanks sir i was so confused about how the entropy part cancels out but you helped to talk about approximation most pople just said in equilibrium entropy change is zero but jere we were talking about stantdard change in entropy
