(a) The work done by the gas during this process is -10.8 J.

(b)  The heat added to the gas during this process is 10.8 J.

Work done by the gas against an external pressure

The work done by the gas during the isothermal expansion is calculated as follows;

W(net) = ΔP x ΔV

W(net) = (2 kPa - 5 kPa) x (6L - 2.4 L)

W(net) = (-3kPa) x 3.6L

W(net) = -10.8 kPa.L

W(net) = -10.8 J

Heat added to the gas

W = - Q

-10.8 J = -Q

Q = 10.8 J
