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.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
