Question

state the zeroth law of thermodynamics name and write the SI unit of the physical quantity defined on the basis of this law​

Answer 1

Answer:

Explanation: Zeroth law of thermodynamic :

It states that if two systems A and B are separately in thermal equilibrium with a third system C, then A and B are also in thermal equilibrium with eachother.

Answer 2

 $T_A=T_B\ \&\ T_B=T_C\ \Rightarrow T_A=T_C$

kelvin being the S.I. unit of temperature.

Explanation:

The first law of thermodynamics states that if a body A is in thermal equilibrium with body B and body B is in thermal equilibrium with body C then we can conclude that bodies A & C are also in thermal equilibrium with each other.

The law only includes the physical property temperature of the bodies which is measured in kelvin (K) in the S.I. units.
