Quizplus · Accepted Answer

Archimedes' Principle explains why a hot air balloon floats. It states that an object immersed in a fluid experiences an upward force equal to the weight of the fluid displaced by the object. In the case of a hot air balloon, the heated air inside the balloon is less dense than the cooler air outside, causing the balloon to displace a volume of air heavier than the balloon and its contents, resulting in lift.
