Heating of water under atmospheric pressure is an
Correct answer: B. Isobaric process
- A. Adiabatic Process
- B. Isobaric process
- C. Isothermal Process
- D. Isochoric Process
Explanation
In an isobaric process, the pressure remains constant while heat is added or removed from the system. When water is heated under atmospheric pressure, the pressure remains relatively constant while the temperature of the water increases, making it an isobaric process.

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.
