Use of hot air balloons in sports and for meteorological observations is an application of
Options
(a) Boyle’s law
(b) Newton’s law
(c) Kelvin’s law
(d) Charle’s law
Correct Answer:
Charle’s law
Explanation:
The Charles’s law is the use of hot air balloons in sports and for meteorological observations gas expands on heating. Since the mass of gas sample is constant, the larger volume at higher temperature will have lower mass per unit volume and therefore lower density. Thus hot air is less dense than cold air. This causes a hot air balloon to rise by displacing cool air of the atmosphere.

The use of hot air balloons in sports and for meteorological observations is an interesting application of Charle’s law. According to Charle’s law, gases expand on heating and hot air is less dense than cool air. This causes a hot air balloon to rise by displacing the cooler air of the atmosphere.
