When the density of air is high, there are more air molecules present in a given volume. This can affect various factors such as air pressure, sound transmission, and the efficiency of combustion processes.
= What is low air density? = well, high or low are relative concepts. Normally the standard air density of the air is defined as the density of the air at 15ºC and at sea level pressure (standard conditions), what give a value of 1,225kg/m3. This way, we can talk about high or low air density related to the standard value. Air density depends on temperature and pressure. The colder the temperature the higher the density is, and the higher the height in the atmosphere the lower the density becomes. In the Everest peak, e.g., air density can be lower than 0,5. Meanwhile in the Antarctica (at sea level) the density could reach values higher than 1,5.
Carbon dioxide has a higher density than air. This is why it can accumulate in low-lying areas and pose a risk of asphyxiation if not properly ventilated.
-- 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.
The speed of sound increases with altitude due to the decrease in air density. This means that at very high altitudes, where air density is lower, the speed of sound will be faster compared to at sea level.
Air pressure decreases from high to low as one moves upwards in the atmosphere due to a decrease in air density. Conversely, air pressure increases from low to high as one moves closer to the Earth's surface where more air molecules are compressed together, creating higher pressure.

As temperature increases, density decreases.
density
As temperature increases, air density decreases because the air molecules have more energy and spread out, causing the air to become less dense. Conversely, as temperature decreases, air density increases because the air molecules have less energy and come closer together, making the air more dense.
The density of air decreases with increasing altitude because air at high altitudes is under less pressure.
When a high density air mass pushes into a low density air mass, the denser air will typically force the less dense air to rise. This can lead to the formation of weather fronts, including cold fronts and occluded fronts, which can result in changes in temperature, precipitation, and wind patterns.
The density of air reduces as height is gained.
Carbon dioxide has a higher density than air. This is why it can accumulate in low-lying areas and pose a risk of asphyxiation if not properly ventilated.
High altitude air density near the equator tends to be lower due to the warmer temperatures causing air to expand, reducing its density. Additionally, high humidity can further decrease air density as water vapor molecules displace nitrogen and oxygen molecules in the atmosphere. These large temperature and humidity swings at the equator can result in more dynamic changes in air density compared to other regions.
-- The density of a closed jar full of air doesn't change, no matter how high you take it. -- The density of the open air in the atmosphere that's all around you decreases steadily as your altitude increases.
because at higher temperature the air become light i.e. density is lower , so it flows from higher density to lower density area.
