In layman terms, warm air rises and cold air sinks (experience that in a two-story building). Lighter objects float to the top. Therefore, warm air has a lower density than cold air.

As a parcel of air increases in altitude its pressure will?
No, the density lowers. When air expands, the volume of area it takes up increases while the density decreases. The molecules move apart.
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.
Does cold air increase or decrease water density?
decrease
What happens to air pressure when density decreases?
density decreases as air pressure increases
Name three factors that affect the density of an air mass?
Density = mass divided by volume. Mass is determined by the individual atoms or molecules and their compression (how close together they are). Compression is affected by external elements such as temperature and atmosphere. Temperature can increase or decrease density (hotter temps lead to decrease in density as atoms separate). Atmospheric pressure can also change the density (air is less dense the further you get from Earth/higher you go in the sky).
Does the air increase or decrease towards the surface with a high pressure?
Air density and pressure increase nearer the surface
How Does temperature affect air pressure and air density?
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.
How does temperature affect air density and air pressure?
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.
When altitude increases does air density?
The density of the atmosphere decreases with altitude.
Why does density of air decrease with increase in height?
The density of air decreases with increasing altitude because air at high altitudes is under less pressure.
What effect does air density have on the absorption and radiation of energy?
An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
As a parcel of air increases in altitude its pressure will?
No, the density lowers. When air expands, the volume of area it takes up increases while the density decreases. The molecules move apart.
How is it that the altitude decrease and the density of the air does what?
Altitude decreases, pressure increase, temperature decreases (some, but less effect than pressure), density goes up.
How are temperature and air mass related?
For a given volume and pressure, the mass of the air contained in that volume (density) will decrease as the temperature increases.
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
What will happen to air if it is heated along a slope element?
Generally, if air is heated, its temperature will increase. And if the pressure remains constant, its density will decrease.
