The average velocity of molecules of nitrogen gas (n2) at room temperature is around 500 m/s. if you were to raise the temperature of the nitrogen gas by 50°c what is a good estimate for the speed of the molecules?
a. 100 m/s
b. 500 m/s
c. 600 m/s
d. 200 m/s

a 100 m/s divied 500 by 50 youl get 10 add a zero and ther u go

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.
