A sample of an ideal gas goes through the process. From Ato B, the process is adiabatic; from Bto C, it is isobaric with 345 kJ of energy entering the system by heat; from Cto D, the process is isothermal; and from Dto A, it is isobaric with 371 kJ of energy leaving the system by heat. Determine the difference in internal energy Eint ,B 2 Eint ,A . 1 3 P(atm) 0.09 0.20.4 1.2 A C B D V(m 3 )

true tan speed = ang vel x radius

no. dot product   =0 when vecs at right angles

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.
