With the pressure held constant at 210 kPa, 98 moles of a diatomic ideal gas expands from an initial volume of 0.75 m3 to a final volume of 1.9 m3. Assume that the change in internal energy of the gas is given by 5/2nRDT. Qn 2 What was the change in the internal energy of the gas?

answer: strength i guess

explanation:

lol

explanation:

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.
