Q. The concept of temperature in thermodynamics is suggested by the

Thermodynamics

Solution:

Zeroth law’ of thermodynamics states that ‘two systems in thermal equilibrium with a third system separately are in thermal equilibrium with each other. This suggests that when two systems A and B are in thermal equilibrium, there must be a physical quantity that has the same value for both. This thermodynamic variable whose value is equal for two systems in equilibrium is called temperature.
