first, find the number of moles of gas.
Now, n=PV/RT at the initial condition
change in work= change in PV
change in work= V dP + P dV
but pressure is constant, so dP=0
change in work= P(finalV-initial V) where V is in m^3, P is in Pascals.
a gas at 10atm pressure occupy a volume of 10L at 300k it is allowed to expand at the constant temperature of 300k under constant external pressure till the volume equilibrate at 100L calculate the work done
