"We can determine pressure's effects on temperature using ideal gas laws.
The Ideal Gas Law is P1V1T1 = P2V2T2 ... Initial pressure (P1) multiplied by the initial volume (V1) and divided by the initial temperature (T1) is equal to the final pressure (P2) multiplied by the final volume (V2) and divided by final temperature (T2). If we are only looking at pressure affecting temperature, we can assume volume is constant and we can ignore it (or assume it is 1 and stays 1).
Let's consider this relationship. If our initial pressure is 1 atm and our initial temperature is 270K, what happens to the temperature when we double the pressure?
Our equation would look like this: 1atm270K = 2atmx (where x is equal to our final temperature).
Solving for x, we find our final pressure doubles to 540 K when we double our pressure. If we were to half our initial pressure, we would see our final temperature would also be halved.
How does this relate to atmospheric pressure and temperature? Well, simply put, pressure change directly effects temperature. If you increase atmospheric pressure by 0.25 atm, your temperature will increase proportionally."
