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.

Why do objects sink or float? :
Objects with a density greater than water will sink, while those with a lower density will float.
Claim
The coin sinks to the bottom of the container, while the piece of wood and the bottle cap float on the surface.
Evidence
Density is the amount of mass per unit volume. Objects denser than water have more mass packed into a given volume and thus sink, while less dense objects have molecules that are less packed in a given volume.
Reasoning
Which object has the lowest density in this picture?
A
B
C
