How does the temperature of the air effect the density of the air?

Answer 1

Well as you increase in altitude the air thins, because you are getting higher in the Earth's atmosphere which has less density then lower atmospheric levels which makes the air thin.

Answer 2

When air is warmer, the particles in the air expand and cause the air's volume to increase. Because density is the mass of the air divided by the volume of the air, and since the mass remained the same, the density decreases, hence why hot air rises and cold air sinks. ~Ares
Temperature increases the speed of air molecules . This molecules collide each other and bounce further than when air is colder causing dilatation of the air. It means that the same amount of air is occupying more volume making it les dense than colder air and making hotter air go up and colder air go down and creating moving air masses called Wind.

Hot air is less dense and is called Low presure system, Cold air is more dense and called High pressure system.

AnswerHeat causes expansion, which reduces an object's density. The tighter together the molecules are the denser the object, when you add heat the molecules expand allowing more freedom of movement between molecules, resulting in lower density of a particular object, such as air.Plus water evaporates.

Answer 3

Air density is the same as air pressure. Pressure is proportional to temperature. If there is more pressure (density) in the air, particles collide together a lot more frequently and increase in temperature. Therefore, if pressure increases, temperature increases.

Answer 4

Scroll down to related links and look at "Density of air - Wikipedia". See: "Importance of temperature".

Answer 5

If the land is cold and wet it will effect the air density by making the air feel moist.

Answer 6

Temperature will decrease air density.

Answer 7

heat causes air to be less dense
