• neurally buoyant, positively buoyant, negatively buoyant

• negatively buoyant, neutrally buoyant, positively buoyant

• positively buoyant, neutrally buoyant, negatively buoyant

• neutrally buoyant, negatively buoyant, positively buoyant

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.
