Cold air falls and warm air rises. Warmer air rises above cooler air because it is less dense. The particles vibrate and move further apart so the molecules that compose the air are more spread out, causing the warm air mass to weigh less than the cool air.ass

What is true A warm air is less dense than cool air B warm air is as dense as cool air. C warm air has no density. D warm air is denser than cool air?
Warm air is less dense than cool air.
Why does water cool faster in the beieging then at the end?
In the beginning of what ? At the end of what ?Do you mean "Why does hot water cool faster than cool water ?" ?Because the rate at which heat passes from a warm object to a cool objectdepends on the difference in their temperatures. So, as the warm objectbecomes less warm and the difference in their temperatures becomes smaller,the rate at which heat flows between them also becomes less.
Does heat travel from warm to cool or cool to warm?
Heat travels from warm to cool.
Cool air is heavier than warm air.where is the best place in a room to put an air conditioner?
cool air is heavier than war air.
What happens to the volume of solids liquids and gasses as they warm and cool?
Mostly they expand as they warm, contract as they cool.
What is true A warm air is less dense than cool air B warm air is as dense as cool air. C warm air has no density. D warm air is denser than cool air?
Warm air is less dense than cool air.
Why is warm air less dense than cool air?
Sooo many fingers

Why does cool air sink and warm air rises?
Because warm air is less dense then cool air.
What effect does cool temperature have on air?
Cool air is denser than warm air, making it less likely to rise. It also cannot hold as much moisture as warm air.
In which direction is heat transferred-from warm to cool to cool to warm?
Heat flows from a region where there is a lot to where there is less.
Does warm air have less molecules than cool air?
If they are both under the same pressure and are the same in volume, then, yes, warm air has fewer molecules
Why the air temperature near the ceiling of the room tends to be warmer than near the floor?
Because warm air rises over cool air. Warm air is less dense than cool air, and it's lifted by buoyancy and floats on the more dense cool air.
Which statement regarding air temperature is NOT trueCool air rises and warm air falls.Air heats up more quickly than land.Warm air is less dense than cool air.Air heats up more quickly than water?
"Cool air rises and warm air falls" is false. Cool air is denser than warm air, and therefore warm air will rise above cold air.
Is warm air dense?
No, warm air is lighter than cold air because hot air rises and cold air stays in the same place.
What zone does the warm are rise and cool and the cool air sinks?
Warm air molecules are fast moving and therefore less dense than cold air molecules. Since cold air is more dense (more slowly moving) it sinks.
Why does convection take place?
Convection takes place because cool air is less dense than warm air.
