Who coined the term ‘zeroth law of thermodynamics’ in 1931, which asserts that two bodies in equilibrium with a third are in equilibrium with each other?

Correct option is D

The correct answer is (d) Ralph H Fowler.
 Ralph H Fowler coined the term ‘zeroth law of thermodynamics’ in 1931.
 The zeroth law of thermodynamics states that if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.
 This law provides a foundation for the concept of temperature and establishes that temperature is a fundamental and measurable property of matter.
 Ralph H Fowler was a distinguished British physicist and astronomer, known for his significant contributions to statistical mechanics and thermodynamics.

James Clerk Maxwell:
 James Clerk Maxwell was a Scottish physicist known for his formulation of the classical theory of electromagnetic radiation.
 He is not associated with the zeroth law of thermodynamics but is famous for Maxwell's equations.
Max Planck:
 Max Planck was a German theoretical physicist who originated quantum theory.
 He is not related to the zeroth law of thermodynamics but is known for Planck's constant and Planck's law of black-body radiation.
Josiah Willard Gibbs:
 Josiah Willard Gibbs was an American scientist who made significant contributions to thermodynamics and physical chemistry.
 He is known for Gibbs free energy and the phase rule but did not coin the term ‘zeroth law of thermodynamics’.
