JEE Main 8 April 2024, Shift 1, Chemistry Q83

Question 83 of 90 in this shift, Chemistry question 23 of 30, Section B.

Consider the figure provided. 1 mol of an ideal gas is kept in a cylinder, fitted with a piston, at the position A, at 18∘18^\circ C. If the piston is moved to position B, keeping the temperature unchanged, then 'x' L atm work is done in this reversible process. x = ____________ L atm. (nearest integer) [Given : Absolute temperature = ∘^\circC + 273.15, R = 0.08206 L atm mol−1^{-1} K−1^{-1}]

The figure, in words

Cylinder with piston; position A marks a volume of 10 L at the bottom; position B is above A with 90 L between A and B.
