studiot Posted June 19, 2017 Share Posted June 19, 2017 I don't have much time tonight but note that going from the second equation to the last [math]T = {\left( {\frac{{\partial U}}{{\partial S}}} \right)_{V,N}}[/math] and [math]P = - {\left( {\frac{{\partial U}}{{\partial V}}} \right)_{S,N}}[/math] so the first term is [math]S\frac{\partial }{{\partial \left( {\lambda S} \right)}}U\left( {\lambda S,\lambda V,\lambda N} \right)[/math] This is therefore ST similarly the second term leads to -PV I will try to do more tomorrow. 1 Link to comment Share on other sites More sharing options...
