A 1.00 mol sample of Hydrogen gas is heated at constant pressure from 300 K to 420 K. Calculate:.a) the energy transferred to the gas by heat, (3.49 kJ)b) the increase in its internal energy and (2.49 kJ)c) the work done on the gas. (-1.00kJ)3)

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.
