Yes, the cool air is lighter than the warm air and that is why Ac's are at the top or high level of the room so in this way when the AC gives out cool air it travels down and the warm air travels upwards and the whole room gets cool quickly.

Does water with a greater volume cool faster than water with a less volume?
NO
What is the properties of a liquid?
Less dense than solid, more than gas; definite volume, but no definite shape; and lighter vescosity than solids.
How will you measure volume of a body lighter than water?
In order to measure volume, one normally sees how much water it displaces. If the body floats, the water displaced will be equal to the weight of the body, not the volume. It will be necessary to force the body down so that it is totally submerged. If there is an anchor and chain below the surface, the water displaced when the body is attached and submerged will have the same volume as the body.
Volume of warm air weighs less than an equal volume of cold air because?
It's less dense
Is a body totally submerged in a liquid displaces a volume of water less than its volume?
A body which is totally submerged in a liquid displaces a volume of water equal to the volume of the body.
What happens because water vapor molecules are lighter than nitrogen or oxygen molecules?
humid air is lighter that an equal volume of dry air at the same temperature.
What element is lighter than helium gas?
Under the same conditions of pressure and temperature, any volumeof hydrogen weighs less than an equal volume of helium.
Why do darker colors get cool faster than lighter colors?
Darker colors absorb more light than lighter colours, hence why they are darker. Therefore they have more energy to release than lighter colours and cool down more rapidly.
What is a cool fact about Titanium?
it is stronger than steel but 42% lighter than it
How the hot air balloon can rise up into the air even through it doesm't have a motor?
A rubber ball rises up in the water because it is full of a substance (rubber) that is lighter than the same volume of water. A hot air balloon rises up into the cool air because it is full of a substance (hot air) that is lighter than the same volume of cool air. The hot air balloon floats in cool air, just like the rubber ball floats in water.
How does a boat stay afloat?
It is lighter than the volume of water which it displaces.
Does water with a greater volume cool faster than water with a less volume?
NO
Would an object that a had a lower density than another item be lighter or heavier than the other item?
given the two objects are of equal volume, the one with a lower density would would weigh less.
Why is ice heavier than lead?
It isn't. How did you get that idea? Ice is much lighter than lead, for the same volume.
Why is a piece of pumice lighter than a piece of obsidian equal size?
Because pumice is lighter than obsidian always. That means obsidian weighs more than pumice.
Why can't we measure the volume of an object if it floats on water?
Simply because the volume of water displaced is not equal to the actual volume of the object. If an object is lighter than water, you have to find another method of determining its volume. ------------------------------------ alternatively you could use a very thin pin to push the object under the water. However, the volume of the submerged portion of the pin would need to be suvtracted from the volume of the object measured.
What is the properties of a liquid?
Less dense than solid, more than gas; definite volume, but no definite shape; and lighter vescosity than solids.
