1.	What are state and path functions? Give two examples.
Answer» Solution :(i) State FUNCTION : A state function is a THERMODYNAMIC property of a system, which has a specific VALUE for a given state and does not depend on the path (or mannery) by which the particular state is reached. Example : Pressure (P), Volume (V), Temperature (T) (ii) Path functions : A path function is a thermodynamic property of the system whose value depends on the path by which the system changes from its initial to final states. Example : Work (w), Heat (Q).
