Question:

In this chapter, from the third law of thermodynamics, it has been shown that the entropy of all substances approaches a common value at 0 K (which for convenience we have taken to be zero). This implies that the value of the entropy at 0 K is not a function of volume or pressure. Use this information to show the following: 

CV = 0 

at T = 0K and that the coefficient of thermal expansion

is zero at 0 K. a= a 1 + (*), V P
