zeroth law of thermodynamics ​

Answer 1

Explanation:

The zeroth law of thermodynamics states that if two thermodynamic systems are each in thermal equilibrium with a third one, then they are in thermal equilibrium with each other. Accordingly, thermal equilibrium between systems is a transitive relation.

Answer 2

Zeroth law of thermodynamics

If the isolated bodies A and B are in thermal equilibrium independently with a third body C, then the bodies A and B will also be in thermal equilibrium with each other.

$\leadsto$ Zeroth law of thermodynamics leads to the concept of temperature.

$\leadsto$ Temperature is the measure of degree of hotness or coldness of the body.

$\leadsto$ Heat always flows from the body at higher temperature to the body at lower temperature

$\leadsto$ Temperature is a scalar quantity.

$\leadsto$ Its SI unit is Kelvin (K) and degree Celsius (°C).

$\leadsto$ It's dimensional formula is M⁰L⁰T⁰K¹
