What work is done by a system on its environment when an ideal gas is maintained at a constant pressure of 200 newtons/meter2 during an isobaric process, while the volume decreases by 0.2 cubic meters? a. 40 joules b. 1,000 joules c. -40 joules d. -1,000 joules

As we know that work done by external environment is given as

here we know that

P = 200 N/m^2

now we will have

so work done by external atmosphere will be 40 J

so correct answer will be

A. 40 joules

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 !

so easy. just google the electromagnetic waves and it’ll pop up.
