Answer 1

Answer:

The zeroth law is incredibly important as it allows us to define the concept of a temperature scale.

If two systems are each in thermal equilibrium with a third, they are also in thermal equilibrium with each other.

For example, consider two separate cups of boiling water. If we place a thermometer into the first cup, it gets warmed up by the water until it reads 100°C. We now say that the thermometer is in thermal equilibrium
