Laws Of Thermodynamics

Thermodynamics is the science of energy transfer and it’s effect on physical properties of a substance. It is based upon observations of common experience which have been formulated into thermodynamic laws. These laws govern the principles of energy conversion. The applications of thermodynamic laws and principles of energy conversion. The applications of the thermodynamic laws and principles are found in all fields of energy technology, notably in steam and nuclear power plants, internal combustion engines, gas turbines, air conditioning, etc.

Zeroth Law Of Thermodynamics

The property which distinguishes thermodynamics from other sciences is temperature. Temperature is associated with the ability to distinguish hot from cold. When two bodies at different temperatures are brought into contact, after some time they attain a common temperature and are then said to exist in thermal equilibrium.

So, Zeroth law of thermodynamics state that ‘when a body A is in thermal equilibrium with body B, and also separately with body C, then B and C will be in thermal equilibrium with each other.’
