- 8. Multiple Choice
As a flame heats air in a hot air balloon it starts to rise. Which of the following statements incorrectly explains the chemistry behind why this happens.
The air molecules become less dense & more bouyant than the cooler air in the surrounding atmosphere.
The volume of the gas increases because the molecules in the gas are spaced further apart.
The mass of the of the gas increases causing density to increase & buoyancy to decrease.
