A 3.50 L gas sample at 20.0 C and a pressure of 650. mm Hg is allowed to expand to a volume of 8.0 L. The final pressure of the gas is 425 mm Hg. What is the final temperature of the gas?

437 K

Explanation:

initial PV/T = final PV/T

(3.50L)(650 mm Hg)/293K = (425 mm Hg)(8.0 L)/T2

7.78 T2 = 3,400

T2= 437 K

more info ? ? i don't understand what the question is

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
