Being a gas, the density of air can vary a lot, depending on its temperature and pressure. At sea level, it is usually close to 1.2 kilograms per cubic meter.

How would heat change the density of a parcel of air?
how heat would change the density of a parcel of air?
When density of air is heated how does it affect air pressure?
cheeseballs! i dont know, but its better to not listen to the advice above The density of air decreases as altitude increases. Air at sea level has more gas molecules in each cubic meter than air at the top of a mountain
Does a cubic meter of air have less mass higher up?
Yes. The density of the air (and thus mass per unit volume) deceases all the way to zero (in space) as the altitude increases.
How does a balloon pilot use density to control the altitude of a balloon?
the pilot heats the air stored in the balloon with a large flame the hotter it gets the higher it goes because the heat changes the density to make it go up or down if the pilot decreases the size of the flame the hot air lowers because the smaller flame has less heat giving it a higher volume, but the air stays the same thus making it lower
Why does sound carry better in the fog?
What's fog? Fog is caused by the condensation of water molecules in air. This leads to the increase in the density in air. So, the layman answer can be: Velocity of sound is greater in Denser materials, so during fog velocity of sound is greater. Mathematicaly: v2=Bulk modulus/density =stress/strain*density we can say stress due to sound wave normally and in fog is constant. Therefore, v2 is inversely proportional to strain*density. during fog this value is less than normal, that's why velocity of sound wave in fog is greater.
How do you think the density of heated air compares to the density of cooler air?
The density of heated air is less than the density of cooler air.
What difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
What is difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
Does air have density and pressure?
Air has both density and pressure.
How does the density of the air affect pressure?
Pressure affects the density of air by increase of pressure increases the density
How do you convert density in air to vacuum in oil?
subtract 0.0011 from the density in vac to get density in air.
What do changes in density cause air movement?
Low density air rises, higher density air moves in to take its place.
Compare the density of water and air?
Air's density is less than that of water. Water's density is almost 800 times greater than air.
How density and temperature of air related?
cold air has higher density, by hot air is opposite
How does altitude affect density and air pressure?
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
What do air density and air pressure have in common?
At a given temperature, the higher the air density, the higher the air pressure.
