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