An ideal gas is enclosed in a cylinder that has a movable piston on top. the piston has a mass m and an area a and is free to slide up and down, keeping the pressure of the gas constant. how much work is done on the gas as the temperature of n mol of the gas is raised from t1 to t2? (use any variable or symbol stated above along with the following as necessary: r.)

Explanation:

Given mass of piston

no. of moles =n

Given Pressure remains same

Temperature changes from

Work done

W=

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.
