However, with 2022 JEE-Main being postponed from April / May to 20–29 June / 21–30 July, JEE-Advanced 2022 was also postponed and subsequently held on 28 August 2022. On 5th November 2024, it is announced by IIT Kanpur , and Joint Admission Board(JAB) that the attempts of JEE-Advanced are now increased from 2 to 3. [ 71 ]

The first part of the book starts by presenting the problem thermodynamics is trying to solve, and provides the postulates on which thermodynamics is founded. It then develops upon this foundation to discuss reversible processes, heat engines, thermodynamics potentials, Maxwell's relations, stability of thermodynamics systems, and first-order phase transitions.
The first and second law of thermodynamics are the most fundamental equations of thermodynamics. They may be combined into what is known as fundamental thermodynamic relation which describes all of the changes of thermodynamic state functions of a system of uniform temperature and pressure.
For quasi-static and reversible processes, the first law of thermodynamics is: d U = δ Q − δ W {\displaystyle dU=\delta Q-\delta W} where δQ is the heat supplied to the system and δW is the work done by the system.
In thermodynamics, Bridgman's thermodynamic equations are a basic set of thermodynamic equations, derived using a method of generating multiple thermodynamic identities involving a number of thermodynamic quantities.

The existence of such states is a basic postulate of classical thermodynamics. [4] [5] This postulate is sometimes, but not often, called the minus first law of thermodynamics. [6] A notable exception exists for isolated quantum systems which are many-body localized and which never reach internal thermal equilibrium.
