Zeroth Law of Thermodynamics
|
Detailed explanation-1: -The zeroth law of thermodynamics states that if two objects are in thermodynamic equilibrium with a third object, then they must be in thermodynamic equilibrium with each other.
Detailed explanation-2: -When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects.
Detailed explanation-3: -A system is said to be at thermal equilibrium when there is no net heat transfer between the constituents of the system. Two objects can only be at thermal equilibrium when the temperatures of both the objects are same. If A and B are in thermal equilibrium with C then A and C also have the same temperature.
Detailed explanation-4: -The zeroth law of thermodynamics states that when two systems, A and B, are in thermal equilibrium with each other, and B is in thermal equilibrium with a third system C, then A is also in thermal equilibrium with C.
Detailed explanation-5: -When there is no temperature difference and the temperature remains constant throughout a system, it is said to be in thermal equilibrium.
