Why are air conditioner placed in a higher level than a lower level?
Cold air will sink and hot air will rise. So ACs are placed up higher.
Why does cold water and air tend to sink?
cold air and water tend denser than hot air and water, so they sink
What can carry heat by convection?
Convection is when fluids (yes, air is considered a fluid) mix... Hot (less dense) molecules will rise as opposed to cold (more dense) molecules will sink.
How does temperature affect air movement?
the hot air will rise and the cool air will sink
How do you make an egg sink?
An egg will sink in water but will float in salt water. An egg will sink faster in hot water than it will in cold water.
Does hot water rise and cold water sink?
HOT rises COLD sinks
What type of water will things float down faster in warm or cold?
Cold will sink to the bottom. Hot water will rise to the top.
Hot air rises cold air sink?
technically hot air does not really rise it is the cold air that sinks below it because it is more dense.
Why does heating the air in hot air balloon make it rise?
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
Why does got air rise and cold air sink?
Hot air is lighter while cold air is heavier. This results in warm or hot air rising and cool or cold air falls.
In the atmosphere a hot air layer is found above a cold air layer How is the separation achieved and why does hot air always tend to rise?
It is because a hot air is a light matter while a cold air is a heavy matter of gas. Like, the difference of low(hot) pressure and high(cold) pressure area.
Why does a hot air balloon rise when it is heated and sink wen it is cooled?
If it is cooled its gets extremely cold from the helium,and when the heat is in the balloon it keeps it warm when its in the helium
Why is the cooling unit of a freezer at the top?
This is because, hot air rises and cold air sinks. When the air near the cooling unit loses heat, it will sink to the bottom whereas the hotter air at the bottom will rise to the top. This is due to the density difference between them, since hot air has a lower density than cold air, hot air will rise. When they rise, they will be cooled by the cooling unit too. And then sink to the bottom again. This cycle will then repeat itself until the air is of a constant temperature.
What happens to thermal energy when you mix hot and cool water together?
Since hot water is less dense that cold air the hot water will rise and the cold would sink then it keeps doing this in a circular motion 'till the thermal energy reaches to thermal equilibrium.
Why are air conditioner placed in a higher level than a lower level?
Cold air will sink and hot air will rise. So ACs are placed up higher.
If nitrogen leaks out from a pipe will it rise up of settle down?
The direction of trave of the nitrogen released will depend on the temperature of both the air in the room and the nitrogen. Cold nitrogen in a hot room will sink, hot nitrogen in a cold room will rise. If both temperaures are about the same the bouyancy will essentially be neutral as air is about 79% nitrogen
Does hot and cold air fall or rise?
Hot air rises and cold air falls.
