- A. Henry's law
- B. The first law of thermodynamics
- C. The second law of thermodynamics
- D. The third law of thermodynamics
Explanation
2nd law of thermodynamics expresses a fundamental and simple truth about the universe, it states that heat cannot flow from colder body to hotter body.

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.
