Explanation / Answer

W = -P*(Vf-Vi)

W = -1atm*(18-1)L

W = -17 atm*L

1 atm*L = 101.32 J

W = -17*101.32

W = -1722.44 J

Q2.

Step 1:

W = -P*(Vf-Vi) = -1.8*(10-1) =-16.2 atm*L = -16.2 *  101.32= - 1641.384 J

Step 2:

W = -P*(Vf-Vi) = -1*(18-10) = -8 atm*L = -8*101.32 = -810.56 J

Wtotal = -1641.384 -810.56 = -2451.944 J
