Enthalpy Dependencies

This text discusses the dependencies of enthalpy with temperature and pressure under the constraints of constant temperature or constant pressure. It also discusses the changes in H with T under constant volume conditions.

Questions

• What are the dependencies of enthalpy as a function of temperature and volume but now under constant temperature and volume conditions?
• What is the relationship between �∂H/∂T�V and Cp?

Answers

• The dependencies of enthalpy as a function of temperature and volume but now under constant temperature and volume conditions are �∂H/∂T�V = Cp + �∂H/∂p�T�∂p/∂T�V and �∂H/∂V�T = �∂H/∂p�T�∂V/∂p�T.
• The relationship between �∂H/∂T�V and Cp is �∂H/∂T�V = Cp + �∂H/∂p�T�∂p/∂T�V = Cp – �∂H/∂V�T.
