Lighter Air Rises at Norris Whitesell blog

Lighter Air Rises. This concept is backed by avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain an equal number of molecules. When gas molecules are warm, they move vigorously. Air density and air pressure are lower. At the heat source of a system of natural circulation, the heated fluid becomes lighter than the fluid surrounding it, and thus rises. Warmer, lighter air is more buoyant than. This is convection, which was described in the plate tectonics chapter. They take up more space. Conventional knowledge has it that warm air rises while cold air sinks. As the density falls, the air become light and starts to rise up and comparatively dense air come down due to the pull of gravity. As hot air from the earth’s surface rises, it soon becomes cold air as it nears space, according to historyforkids.org. Warmer, lighter air is more buoyant than the cooler air above it, so it rises. At the heat sink, the nearby fluid becomes denser as it cools, and is drawn downward by gravity. Contrary to common belief, humid air is lighter than dry air because water vapor molecules replace the heavier nitrogen and oxygen molecules in the atmosphere. The cooler air then sinks down, because it is denser than the air beneath it. This is called a convection current.

As hot air from the earth’s surface rises, it soon becomes cold air as it nears space, according to historyforkids.org. As hot air cools it sinks back to the surface of the earth, where it gets warmed by the ocean only to rise again. They take up more space.

This concept is backed by avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain an equal number of molecules. But a study from the university of california, davis, found. As the density falls, the air become light and starts to rise up and comparatively dense air come down due to the pull of gravity. The cooler air then sinks down, because it is denser than the air beneath it. When gas molecules are warm, they move vigorously. As hot air cools it sinks back to the surface of the earth, where it gets warmed by the ocean only to rise again.
