When the air is warm, the volume and the air pressure increases. When it is cooled, the volume and the air pressure decreases.

its not!

The air pressure will increase if the volume is not permitted to increase. A tire, after a car has been driven for a while, will have a higher temperature, higher pressure, and slightly higher volume (the tire expands slightly) than when just starting out and the tire is cold.

No this is only partially true because when you warm air the volume will increase as volume and temperature are directly proportional, but pressure and volume are inversely proportional so if the volume increased the pressure will decrease.

if the air you are warming were in some type of container then as the temperature rose the air would expand which increases the volume. pressure is inversely related to volume in this case so as the air expands the pressure would decrease. another case would depend on what you mean by "air". substances with different properties all behave in differtent ways. for example water expands as temperature decreases.

NO! It's wrong. Volume and pressure are inversely proportional.
When the temperature goes up, volume increases coz of expansion and pressure will decrease. When temperature goes down, volume will decrease and pressure goes up.

It is true, but, negligible. The pressure of air is 14.7 psi at sea level. You guessd it. Pressure is most strongly effected by elevation. Either up a mountain or down into the ocean. Of course the density of water makes for a much larger change in pressure. For instance, you have to travel 33,000 ft into the air for a 14.7 psi decrease in pressure on your body. 33 ft deep in the ocean will see a 14.7 psi increase on your body.

Yes: Volume will increase:
Pressure will increase due to an increase in the humidity.
Higher temperature increased water vapour.

:( i do no longer think of that is undesirable. My first time became undesirable, yet by way of fact i became too youthful and lost it to the incorrect individual. yet i did no longer lose it by way of be sure rigidity, i lost it by way of my stupidity. yet I found out my lesson. Now that i've got been with somebody for a sturdy 3 years, doing that's superb and it would not experience grimy or like i'm getting used. i think of as quickly as you come across a sturdy guy/female then it's going to all experience maximum appropriate. :)

WRONG. Ieshwar is right, pressure and volume are inversely proportional.
