The process in which both temperature and pressure remain constant is:
Correct answer: D. Impossible
- A. Isothermal
- B. Isobaric
- C. Isochoric
- D. Impossible
Explanation
For an ideal gas (PV = nRT), constant temperature and pressure imply constant volume, which contradicts process with changing state. Thus, such a process is impossible.

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.
