For the ideal gas equation PV = RT, find an expression for (partial differential P/partial differential V)_T by using the method of implicit differentiation (make sure you show all your work). Compare your answer to the result you get by first solving for P in the ideal gas equation and then taking the derivative. b) Repeat part (a) for the van der Waals equation of state.
4. The enthalpy H may be written as a function of temperature T and pressure P. If we have a system whose composition remains constant and using Maxwell's equations and the total differential, we can write dH as avdP where Cp is the heat capacity at constant pressure and the subscript of P on the partial derivative represents the partial of volume with respect to temperature holding pressure connstant. Find the change in enthalpy (A) for an ideal gas undergoing...
