Agas in a cylindrical closed container is adiabatically and quasi-statically expanded from a state a (3 mpa, 2 l) to a state b with volume of 6 l along the path 1.8 pv =constant.
(a) plot the path in the pv plane.
(b) find the amount of work done by the gas and the change in the internal energy of the gas during the process.
