Question

state the zeroth law of thermodynamics? how it leads to the concept of temperature

Answer 1

$\large\fbox\red{Answer}$

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.

The zeroth law is a consequence of thermal equilibrium and allows us to conclude that temperature is a well-defined physical quantity. The zeroth law of thermodynamics states: If they are the same temperature then they will be in thermal equilibrium with each other.
