For isothermal process, change in temperature i.e #delT =0# so,change in internal energy(#delU#) is also zero.

So,from 1st law of thermodynamics we can say, #del Q=del W#

And it's value is expressed as #nRTln((Vf)/(Vi))# (where,#n# is the nos of moles,#R# is universal gas constant,Vf is the final volume of the system and #Vi# is the initial one,#T# is temperature in Kelvin)

Here, #n=1#,#T =(273+27)# or #300 K#, #(Vf)/(Vi) =10#,#R=8.31# SI units

So, #del Q = del W# = #5740.344# Joule
