air pressure and air temperature related?

Question

ok so how are air pressure and air temperature related, and what is one experiment you could do to show the relationship between the two.

Answer 1

We know that pressure is proportional to the product of the density of the air and the temperature of the air by the Equation of State. To understand the behavior of a gas such as the air, it is necessary to hold one variable constant and investigate the relationship between the remaining two. For example, if we hold the density constant then as the pressure is raised so is the temperature and visa versa

Answer 2

Yes, watch the equation for the perfect gases:
To * Po = T1 *P1

Experiment: have a metal container with a known volume and attach firmly to it a Manometer and a bimetal Thermometer, fill it with some gas, let us say simple AIR, Then start heating gently, you will see not only the temperature start raising, but also the pressure, volume is neglected because it does not change. The beautiful of this experiment is that always your values in the instruments will be in equilibrium according to the above equation.

Answer 3

The relationship between air pressure and temperature is inversely proportional. Temperature is a measure of heat energy. As air pressure rises, temperature falls because greater pressure means the air molecules are condensed. As air pressure falls, temperature rises because the air molecules can move more. Movement creates heat energy, and temperature is a measurement of heat energy.

Answer 4

Since you ask under the 'weather' topic, I assume you are interested in the meteorological aspect of it, and not the laboratory.

As pressure decreases, air cools down, and vice-versa. That's the adiabatic effect that you can find e.g. in a refrigerator.

In meteorology, a high pressure sees air sinking and warming up. In a low pressure, the inverse happens. If you look e.g. at a temperature map at 500 hPa (often used by aviators) you'll see that low pressure regions are colder. It may sound a bit paradoxical because the reason the low pressure exist is partly due to the fact that saturated air cools down slower than dry air. In fact, twice as slowly. It takes 200 meters to cool down air at dew point for 1 degree centigrade, and only 100 meters for dry air. The reason is: in order to condense as droplets, water need to release energy in the form of heat.

Answer 5

Look up "Charle's Law" in chemistry for relation of gas temperature, pressure and volume.

Answer 6

Yes, they are cousins.
