What is an adiabatic process?

 What is free energy in terms of thermodynamics?

Define extensive properties.

 How are internal energy change, free energy change and entropy change are related to one another?

 How is entropy of a substance related to temperature?

Define intensive properties.

What is Gibbs Helmholtz equation?

hat is a spontaneous change? Give one example.

 When liquid benzene is oxidised at constant pressure at 300 K, the change in enthalpy is -3728 kJ. What is the change in internal energy at the same temperature?
