A piston–cylinder device, whose piston is resting on a set of stops, initially contains 3 kg ofair at 200 kPa and 27◦C. The mass of the piston is such that a pressure of 400 kPa is requiredto move it. Heat is now transferred to the air until its volume doubles. Determine the workdone by the air, and the total heat transferred to the air, during this process. Also show theprocess on ap–Vdiagram

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.

the ima (higher than 1m) will be greater than the ima with the height of 1m.
