Asample of helium gas occupies a volume of 156.0 ml at a pressure of 733.0 mm hg and a temperature of 337.0 k. what will the volume be at a pressure of 490.0 mm hg and a temperature of 807.0 k? the combined gas law equation is given below. p1v1 t1 = p2v2 t2 in this equation, p1, v1, and t1 are the initial pressure, volume, and temperature, respectively, and p2, v2, and t2 are the final pressure, volume, and temperature, respectively. ml

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.

continuous conducting path for current, power supply

i believe the answer is a hope it and is correct
