Question

Give its physical significance of thermodynamics

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.

The significance of the first law of thermodynamics is listed below-

• It gives the relationship between heat and work.

• It is merely the law of conservation of energy generalised to include heat as a form of energy transfer.

• The energy of an isolated system remains constant.

• Heat and work are different forms of the same entity called energy.

• Heat and work are equivalent to each other.
