Question

What does the zeroth law of thermodynamics allow us to define?

Answer 1

Explanation:

Zeroth law of thermodynamics states that when two thermodynamic systems are in equilibrium with a third system then all of them are in thermal equilibrium with each other.

For example, system A is in thermal equilibrium with system B and system B is in thermal equilibrium with system C then it means system A is also in thermal equilibrium with system C.

Answer 2

The Zeroth Law of Thermodynamics states that if two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other. Credit: Tim Sharp
