A real gas is changed slowly from state 1 to state 2. During this process no work is done on or by the gas . This process must be :

Isovolumic

Explanation:

In thermodynamics, the process whereby A real gas is changed slowly from state 1 to state 2 and in this process there's no work done on or by the gas is called Isovolumic 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 !
