Dependence of entropy on pressure at constant temperature

(dS,dP) at constant T

The dependence of entropy temperature is simple known. It is heat capaity over temperautre. How about the dependence of entropy on pressure at constant temperature?

At a first glace, it cannnot be simply obtained. We can derive this dependence using a property relation. With the help of the property relation, the dependence of entropy on pressure can be expressed with more familar form: the temperature dependence of volume. Numerical excercise is provided for an ideal gas and a solid.
