Question

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

Answer 1

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.
