Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 26: Laws of Thermodynamics

Laws of Thermodynamics

The laws of thermodynamics describe the physical measures, such as energy, temperature, and entropy that distinguish thermodynamic systems at thermodynamic equilibrium.

The Zeroth Law of Thermodynamics

If two systems that are thermodynamic in nature and are each in thermal equilibrium with a third one, then they are said to be in thermal equilibrium with each other, then it represents the zeroth law of thermodynamics. Therefore, the thermal equilibrium between structures is a transitive relation.

The First Law of Thermodynamics

The first law of thermodynamics is a form of the law of conservation of energy, modified for thermodynamic procedures, differentiating two kinds of transmission of energy, as heat and as thermodynamic work, and connecting them to a function of a body’s state, known as Internal energy.

The Second Law of Thermodynamics

The second law of thermodynamics describes that the total entropy of an inaccessible system can never reduce over time, and is continuous if and only if all methods are reversible. Isolated systems naturally change towards thermodynamic equilibrium, the state with the highest entropy.

The Third Law of Thermodynamics

The Third law of thermodynamics can be defined if, regarding the characteristics of closed systems in thermodynamic equilibrium: The entropy of a system tactics a continuous value as its temperature tactics absolute zero.

Reversible and Irreversible Processes

A reversible process is a procedure whose direction can be reverted to its original location by bringing infinitesimal changes to some property of the system via its atmospheres. Throughout the complete reversible process, the system is in thermodynamic equilibrium with its atmospheres. 

Any process that takes place naturally without doing work is known as an irreversible process. An example of an irreversible process is the straight transfer of heat from a hot object to a cold object.
