sf(1.72color(white)(x)"kJ")

Explanation:

The Ideal Gas Equation tells us:

sf(PV=nRT)

:.sf(P=(nRT)/V)

For an isothermal process, the work done in expanding the gas is given by:

sf(W=int_(V_i)^(V_f)P.dV)

:.sf(W=nRTint_(V_i)^(V_(f)).(dV)/V)

sf(W=nRTln[(V_(f))/(V_i]])

sf(W=1xx8.314xx298xxln[0.02/0.01])

sf(W=1717.32color(white)(x)J)

sf(=1.72color(white)(x)kJ)
