Limiting Values for Thermal Properties at Zero Kelvin

3b Limiting Values for Thermal Properties at Zero Kelvin 

The Third Law predicts that lim SV = 0. It follows that St must become 

These relationships can be used to calculate limiting values for several thermal properties as the temperature approaches zero Kelvin. 

Coefficient of Expansion The change in entropy with pressure is related to the coefficient of expansion by 

Since V remains finite at 0 Kelvin, a must go to zero. Thus,
