earth science q about air pressure and heat...?
please someone explain this seeming contradiction to me?
--Heating and Cooling of air by expansion and compression---
when a gas expands, its temperature decreases; when a gas is compressed, its temperature increases. thus when air rises in the atmosphere, it expands and its temperature decreases; similarly, when it descends, it is compressed and its temperature increases.
---effect of temperature on air pressure---
changes in the temperature of the air cause changes in air pressure. as the temperature of air increases, the air expands and its density and pressure decrease. decreasing temperature has the reverse effect.
Um. I don't see the problem. But...
Heat, Cool, Expansion, Compression
(1) Gas bigger, temp lower --> start with energy X, increase the volume that energy X is contained in, so you have the same amount of X, but in a bigger volume, so temp goes down (gas molecules aren't bumping into each other as much)
(2) Other way around. You take energy X and press it into a smaller volume, temperature must go up, because the gas molecules are bumping into each other more - because there's less room to move without bumping
(3) Air rises, air becomes thinner, so the gas can expand (just like a balloon). X is now in bigger volume, fewer bumping molecules, lower temperature
(4) Same thing, but backward, dealing with #2
Temperature and Pressure
(1) Air is just a gas. When a gas is heated, it expands (bumping molecules want out), which lowers the pressure from volume X to volume X - 1. Its density is lower because D=M/V. The less mass in the same volume, the less density.
(2) And, yeah... the other way around.
Not really sure what's confusing. Were you paying attention?
