Which Hot-Air Balloon Will Rise Higher: Warm Air or Hot Air?

Question:

If two hot-air balloons are filled at the same time, but one is filled with warm air and one is filled with hot air, which balloon do you think will rise higher?

A. The balloon with hot air

B. The balloon with warm air

Answer:

The balloon with hot air will rise higher.

When two hot-air balloons are filled at the same time, one with warm air and one with hot air, the balloon filled with hot air will rise higher. This is because of the difference in densities between the two types of air.

Density of an object is defined as the mass per unit volume of the object. It is considered as the measure of the amount of substance in a given space. In this scenario, the hot air balloon filled with hot air has a lesser density compared to the balloon filled with warm air.

When hot air is filled into the balloon, its temperature increases, causing its volume to increase and its density to decrease. The buoyancy of the balloons is affected by their densities, with the less dense hot air providing greater buoyancy.

As a result, the balloon filled with hot air will be able to rise higher in the air than the one filled with warm air. Therefore, the hot air balloon will reach greater heights due to its lesser density and increased buoyancy.
