Water vapor inside an aluminum can has a pressure of 1.00 atm at a temperature of 120.°С. What is the pressure of the gas when the
temperature is dropped to 100.°C?*

P2 = 0.95atm

Explanation:

Using Gay Lussac's equation as follows

P1/T1 = P2/T2

Where;

P1 = initial pressure

T1 = initial temperature

P2 = final pressure

T2 = final temperature

According to the information provided in this question; P1 = 1.00atm, T1 = 120°C, P2 = ?, T2 = 100°C

We need to convert temperature in °C to K

T1 (K) = 120°C + 273K = 393K

T2 (K) = 100°C + 273K = 373K

Hence;

P1/T1 = P2/T2

1.00/393 = P2/373

373 × 1 = 393 × P2

373 = 393P2

P2 = 373/393

P2 = 0.949

P2 = 0.95atm

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.
