cold air because when the temperature drops hot air rises and cold air comes to ground level,cold water and hot water have the same density.

Why is air more buoyant than water?
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
Why does heat rise and how does cold drop?
Cold air is compact air Hot air is less dense than cold air Ergo, hot air rises ; cold air sinks
Do heated air particles become more or less dense?
Things (almost everything, including air) becomes less dense when it is heated. So warm air rises, and cold air falls.
Does hot air move into cold air or does cold air move into hot air?
Both. Since hot air is less dense than cold air, the hot air rises as the cold air falls (i.e. as the cold air displaces the hot air). If you were to dye hot air & then inject it into the center of a room, you would observe the dyed hot air rising. What you may not realize is that gravity draws the (invisible) surrounding dense cold air downwards as it displaces the (visible) less dense dyed hot air. === Previous Posters Answer: Hot air rises
Why does hot air or liquid rise?
It will rise because it has less density, so it tends to "float" on the denser, cold, air.The reason it is less dense is because when you heat air, its volume increases. Since density is mass/volume, the density decreases in this case.
What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
When dense cold air meets less dense warmer air the air is pushed?
When dense,cold air meets less dense,warmer air, the warm air is pushed up
When dense cold air meets less dense warm air the air is pushed?
When dense,cold air meets less dense,warmer air, the warm air is pushed up
When dense cold air meets less dense warmer air the warm is pushed?
When dense,cold air meets less dense,warmer air, the warm air is pushed up
Is warm air less dense than cold air and moist air is more dense than dry air?
Warm air is less dense then cold air. But moist air is actually less dense than dry air because water vapor has a lower molecular weight than the oxygen and nitrogen that make up most of the atmosphere.
When dense cold air meets less dense warmer air the warm air is pushed?
The heavier cold air sinks and slides under the warm air and forces it upward. This causes cumulus and cumulonimbus clouds to form. This brings in the rainstorms and thunderstorms.
Does air change when is cold?
air becomes less dense
Is warm air less dense than cold air?
yes
What is Warm air is less dense than cold air?
it rises
Why does cold gases and liquids sink?
Hot air is less dense than the surrounding air and therefore it rises. Cold air, on the other hand, is the opposite. It is more dense than surrounding air and sinks.
Is air more of less dense then water?
No everything is layered in density, water is much more dense than air. The whole planet is organized based on density with the core being the most dense and the exosphere being the least dense.
Cold air is than warm air?
Cold air is more dense and less buoyant than warm air.
