JEE Main 6 April 2026, Shift 1, Physics Q50

Question 50 of 75 in this shift, Physics question 25 of 25, Section B.

A certain gas is isothermally compressed to (13)rd\left(\frac{1}{3}\right)^{\mathrm{rd}} of its initial volume (V0=3V_0=3 litre) by applying required pressure. If the bulk modulus of the gas is 3×1053\times10^5 N/m2^2, the magnitude of work done on the gas is ________ J.
