Answer 2

Hie dear,

◆ Zeroth Law Of Thermodynamics -
- It states that if two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other.
- We can define *temperature* by zeroth law.

◆ First Law Of Thermodynamics-
- It states that the change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings.
- We can define *internal energy* based on this law.

Hope this is helpful...
