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.
===============================
No, the density lowers. When air expands, the volume of area it takes up increases while the density decreases. The molecules move apart.
Air becomes heavier when it is warm because the heat causes the air molecules to move faster and spread out, decreasing the air density. This decrease in density leads to a decrease in air pressure, making it feel "heavier" compared to cooler, denser air.
When air expands, its pressure decreases while its temperature decreases simultaneously. This is due to the decrease in density as the air molecules move further apart, resulting in lower pressure. The decrease in pressure causes the air to do work on its surroundings, leading to a drop in temperature through the expansion cooling effect.
As altitude increases, air pressure and density decrease because there are fewer air molecules moving closer together due to gravity. This results in lower air pressure and overall density at higher altitudes. On the other hand, as temperature increases, air molecules expand and move further apart, causing a decrease in air pressure and density.
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.
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.

The density of air decreases with an increase in height due to the decrease in pressure and temperature with altitude. As you go higher in the atmosphere, there are fewer air molecules present, leading to lower air density.
Humidity is related to air pressure because as the amount of water vapor in the air increases, the air becomes less dense. This decrease in density leads to a decrease in air pressure. Conversely, when the air is dry, it is denser and the air pressure is higher.
Decrease. As altitude increases, the air density decreases because the air molecules are more spread out, resulting in lower pressure and less mass per unit volume. This leads to thinner air at higher altitudes.
As you go higher in altitude, the air becomes less dense, meaning there are fewer air molecules above you exerting pressure. This decrease in air density leads to a decrease in atmospheric pressure as you ascend in altitude on Earth.
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.
At the bottom of the troposphere
No, the density lowers. When air expands, the volume of area it takes up increases while the density decreases. The molecules move apart.
The density of a balloon will decrease when the amount of air inside it decreases, causing it to become less dense compared to its surrounding environment. This decrease in density may happen if air leaks out of the balloon or if the balloon is subjected to a higher altitude where the air pressure is lower.
As altitude increases, air pressure decreases because there are fewer air molecules pressing down from above. This decrease in air pressure also leads to a decrease in air density. Additionally, the amount of oxygen decreases as altitude increases, making it harder to breathe at higher altitudes.
Altitude decreases, pressure increase, temperature decreases (some, but less effect than pressure), density goes up.
