Zeroth Law Of Thermodynamics

Explanation

### Step-by-Step Text Solution for the Zeroth Law of Thermodynamics

**Step 1: Introduction to the Zeroth Law**
The Zeroth Law of Thermodynamics is fundamental in understanding thermal equilibrium and temperature. It was formulated after the first and second laws of thermodynamics, but it is termed 'zeroth' because it lays the groundwork for defining temperature.

**Step 2: Definition of Thermal Equilibrium**
Thermal equilibrium occurs when two bodies are at the same temperature and there is no net heat flow between them. If two bodies A and B are each in thermal equilibrium with a third body C, then A and B must also be in thermal equilibrium with each other.
