JEE Main 2025 — 23 January, Morning Shift — Question 57

Match the List-I with List-II

List -I	List -II
A	Pressure varies inversely with volume of an ideal gas.	I	Adiabatic process
B	Heat absorbed goes partly to increase internal energy and partly to do work.	II	Isochoric process
C	Heat is neither absorbed nor released by a system	III	Isothermal process
D	No work is done on or by a gas	IV	Isobaric process

Choose the correct answer from the options given below :

$\quad \mathrm{A} \rightarrow \mathrm{P} \propto \frac{1}{\mathrm{~V}}$

$\Rightarrow \mathrm{PV}=$ constant

$\Rightarrow \mathrm{nRT}=$ const. $\Rightarrow \mathrm{T}=$ const.

Hence Isothermal III

$\mathrm{B} \rightarrow$ IV

$\mathrm{W} \neq 0, \Delta \mathrm{U} \neq 0, \Delta \mathrm{Q} \neq 0$ [only isobaric]

$\mathrm{C} \rightarrow \mathrm{I} \Delta \mathrm{Q}=0$ Adiabatic

$\mathrm{D} \rightarrow \mathrm{II}$ w $=0$ Isochoric

III IV I II
