2 liters of N2 at 0 degree Celsius and 5 atm pressure are expanded isothermally against a constant pressure of 1 atm until the pressure of the gas is also 1 atm. Assuming the gas to be ideal, what are the values of work,delta E, delta H, and q for the process?

2. P1 V1 =P2V2 ,
P1=5atm, V1= 2litre, P2=1atm find v2 by above eq.
then put it into -
-px(V2-V1) where pexternl = 1atm
so - 1(10-2)= - 8litreatm
1 litre atm =101.3 joules so multiply it
-8× 101.3 = - 810.4joule
