Which has greater volume, hot air or cold air?

Answer 1

Here is the scientific answer to your question. It is not dependent only on temperature but also on pressure. The equation which governs this is the Equation of State which says PV = RT

where P is the pressure, V is the volume, R is the universal gas constant, and T is the temperature. So if air is heated and the pressure on it is decreased the volume will increase, but if the pressure increases the volume will actually decrease. Use this equation now to answer your question directly. Keep the pressure constant but vary T and allow V to vary.

Answer 2

By some means if you take equal weight of hot and cold air ,the hot air will have more volume.

Answer 3

An equal volume of each is EQUAL.

Now if you have a given volume of COLD air and heat it up, it will expand into a great volume of HOT air, assuming pressure remains constant. If the COLD air is contained in a tank and you heat it up, the volume will remain the same but the pressure will go up.

Answer 4

Volume is a measurement of occupied space.
So, 1 cubic foot of hot air is the same as 1 cubic foot of cold air.

Cold air is more dense than hot air, which means that 1 cubic foot of cold air will weigh more than 1 cubic foot of hot air.

Answer 5

A badly worded question. 1 L of air has the same volume as any other.

Air expands as it warms, and becomes less dense, if that is what you mean.

Answer 6

hot air

Answer 7

This is not a valid question because for a given mass of gases you have to metion three parameters
i-volume
ii-temprature
iii-pressure

Answer 8

hot air.
