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.

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. ...

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. ...
Asked in Physics, Hot Air Balloons
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. ...
Asked in Noble Gases
Why does a balloon filled with helium rise while a balloon filled with an equal volume of average atmosphere air does not?
Helium is lighter than air. More precisely, it is less dense.
Asked in Physics
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. ...
Does a heavier object have a higher volume than a lighter object?
not necceserily, depends on the density
Asked in Nuclear Energy, Physics
How does a balloon stay up in the air?
It's buoyancy - the same as a ship floating in water. In this case the volume of the balloon must weigh less than an equal volume of air. (That's done by using a lighter than air gas - hydrogen, helium, or just heated air.) ...
Asked in Physics
If an object floats the volume of displaced water is equal to the volume of what?
It is not equal, it is less than the volume of the object. When an object floats, the weight of the displaced water equals the weight of the floating object. ...
Asked in Science, Math and Arithmetic, Physics, Volume
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. ...
Asked in Earth Sciences, Physics
Which has more volume 1 kg of water or 1 kg of lead?
1 kg of water. Water is less dense than lead. This means that the same volume of water will be lighter than the same volume of lead. Reversing this, 1kg of water will have a larger volume than 1kg of lead. ...
Asked in Weight and Mass
Is a pound of feathers lighter than a pound of bricks?
No. They are equal mass as they both weighed a pound.
Asked in Physics
Why does same sized piece of wood is lighter than iron piece?
The wood is "lighter" (weighs less; has less mass) than the iron because of it's density. Iron has a greater density than wood, and density is defined as mass/volume, so having the same volume (size), the iron will have a greater mass. ...
Asked in Units of Measure
Is six grams equals to 6 cc?
Six grams of WATER is equal to 6 cc of water, but other things that are lighter or heavier will not make that equation. For example, 6 grams of lead will have much less volume than 6 cubic centimeters, and six grams of Styrofoam will have more volume than 6 cc. ...
Asked in Cooking Measurements, Speed of Light
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. ...

How much is 1.8 liters?
A liter is a unit of volume, equal to a cubic decimeter. If you are accustomed to U.S. measurement, a liter is a bit more than a quart. A liter is a unit of volume, equal to a cubic decimeter.
