1.	What are state and path functions? Give two examples.
Answer» The variables like P. V, T and ‘n’ that are used to describe the state of the system are called as state functions. For example, pressure, volume, temperature, internal energy, enthalpy and free energy A path function is a thermodynamic property of the system whose value depends on the path or manner by which the system goes from its initial to final state. For example, Work (w) and heat (q).

The variables like P. V, T and ‘n’ that are used to describe the state of the system are called as state functions.

For example, pressure, volume, temperature, internal energy, enthalpy and free energy

A path function is a thermodynamic property of the system whose value depends on the path or manner by which the system goes from its initial to final state.

For example, Work (w) and heat (q).
