(C) $\mathrm{P}_{2} \mathrm{V}_{2}=\mathrm{P}_{1} \mathrm{V}_{1}$ (B) The work done on the gas is less when it is expanded reversibly from $\mathrm{V}_{1}$ to $\mathrm{V}_{2}$ under adiabatic conditions as compared to that when expanded reversibly from $\mathrm{V}_{1}$ to $\mathrm{V}_{2}$ under isothermal conditions. SHOW SOLUTION Toughest: Physics section of JEE Main-2014 can be considered as the most difficult among all the sections. The final internal pressure, volume and absolute temperature of the gas are $P_{2}$, $\mathrm{V}_{2}$ and $\mathrm{T}_{2}$, respectively. In this process, the change in entropy of surroundings $\left(\Delta \mathrm{S}_{\text {surr }}\right)$ in $\mathrm{J} \mathrm{K}^{-1}$ is –, For a reaction taking place in a container in equilibrium with its surroundings, the effect of temperature on its equilibrium constant K in terms of change in entropy is described by, An ideal gas is expanded from $\left(p_{1}, V_{1}, T_{1}\right)$ to $\left(p_{2}, V_{2}, T_{2}\right)$ under different conditions. The point at which the entire mass of the body or the system of a particle is concentrated is called the centre of the mass of a body or system of a particle. Assuming the gas to be ideal the work done on the gas in taking it from A to B is :- Calculate (a) the final temperature of the gas and (b) change in its internal energy. 41 Years IIT-JEE Physics (1979-2019) Chapter Wise & Topic Wise Solved Papers Every aspirant must check the JEE Main/Advanced previous year question papers to understand the nature of the exam.
