SSC CGL - 27 July 2023 - Shift 3 • General Awareness • Q44

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?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Ralph H Fowler.

The term "zeroth law of thermodynamics" was introduced by Ralph H. Fowler in 1931 made important strides in refining and defining the concept of temperature.

This law states that if two systems are each in thermal equilibrium with a third system, they must also be in thermal equilibrium with each other. This fundamental principle is crucial for setting up a consistent temperature scale and understanding how temperature can be measured and compared across different systems.
