Mention the significance of Zeroth's law of Thermodynamics.

The zeroth law explains the thermal equilibrium which is when two bodies are in contact with each other, they maintain equal temperature.

There is no net change in temperature between the two systems.

If two systems A and B are in thermal equilibrium with system C, then both are in thermal equilibrium with each other.

The zeroth law of thermodynamics maintains the system in thermal equilibrium.
