Which of the following cannot determine the state of the thermodynamic system?
Correct answer: D. P and R
- A. P and V
- B. P and T
- C. T and V
- D. P and R
Explanation
Option D is correct as to find the state of the thermodynamic system, we need "P", "V", or "T". If we have any two, we can find the state. If we only have one, then it is not possible to find the state of the system.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
