Calculate the internal energy change for each of the following. a one hundred (100.) joules of work are required to compress a gas. at the same time, the gas releases 43 j of heat. j submit b a piston is compressed from a volume of 8.60 l to 1.10 l against a constant pressure of 2.00 atm. in the process, there is a heat gain by the system of 360. j. j c a piston expands against 1.00 atm of pressure from 14.5 l to 32.0 l. in the process, 1037 j of heat is absorbed.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

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.
