WebWhen we studied mid-latitude cyclones, you saw a number of mechanisms that cause air to rise, such as overrunning and low-level convergence along a cold front. But, these mechanisms that cause rising air result in fairly slow upward motions, often roughly a few or several centimeters per second (at most maybe 10 to 20 centimeters per second). WebJun 4, 2011 · The true reason that heat rises is due to something not yet mentioned... GRAVITY! To be more precise, in a positively excited atom/molecule, the electrons create a larger orbital shell whereby...

WebThe mechanism responsible for the rising of hot air is flotation: Hot air is less dense than cold air and hence air pressure will exert an upwards force, in the same way air rises in water. Now if cold air was magically unaffected by gravity, then it would not be able to exert pressure on the hot air and thus it would not rise. WebAs air pressure decreases, the density of the air decreases. So density decreases as altitude increases. Since the air is less dense at a high altitude, there are fewer air … facebookcampusk9
Does hot air really rise? - Physics Stack Exchange
WebMay 29, 2024 · The gravity will have influence on both "objects", the lighter one will rise, the heavier one will fall. An empty balloon with no air in it falls, so why does a helium filled … WebRising, warmer, less-dense air creates an area of lower pressure underneath. Sinking, cooler, more dense air creates an area of higher pressure underneath. Altitude affects air pressure by as you go up in the atmosphere you will notice that there is less and less air molecules and they are more spaced out.
