Professor PC Thomas Classes · Answer

(b) : In thermodynamics, path variables are quantities whose values depend on the specific path taken during a process between two states. Heat (B) and Work done (E) are path variables. Internal energy, temperature, and volume are state variables because they depend only on the current equilibrium state of the system.
