1.5 kg of argon (m=39.94) at 1.025 bar and 30°c in a closed system is compressed reversibly and adiabatically according to the law pv=constant until the pressure is 4.10 bar. calculate (i) the initial and final volumes (ii)the final temperature (iii) the workdone

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
