Define the state function and state variables. Give examples.

Text Solution

Verified by Experts

State function : Properties of the systems which depends on the initial and the final states of the system but are independent of the path are called state functions.
Eg. : Energy, Volume, Enthalpy, Gibbs Energy.
State variables : Variables like PVT are called state variables. These are used to describe a system completely.
