2024 Re-NEET ThermodynamicsThermodynamic state variables Medium Question 7 of 54 in Thermodynamics

The equilibrium state of a thermodynamic system is described by A. Pressure B. Total heat C. Temperature D. Volume E. Work done. Choose the most appropriate answer from the options given below.

A A, B and E only
B B, C and D only
C A, B and C only
D A, C and D only

The answer is D.

Solution

The equilibrium state of a thermodynamic system is described by its state variables: Pressure (A), Volume (D) and Temperature (C). Total heat (B) and Work done (E) are path variables, not state variables. So the correct set is A, C and D only.
