2. What is the temperature when the volume is 4L? The original temperature is 200K and the
original volume is 5L.

160

Explanation:

p*v/t = constant

or

p1*v1/t1 = p2*v2/t2

pressure is not stated in question so we get rid of it on both sides

v1/t1 = v2/t2

we are finding temperature so we flip the entire equation

t1/v1 = t2/v2

200/5 = t2/4

4(200/5) = t2

=160

Yes it is 160K as the first person said

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.
