Front

As a flame heats air in a hot air balloon it starts to rise. Which statement incorrectly explains why this happens?

• The air molecules become less dense & more buoyant 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 gas increases causing density to increase & buoyancy to decrease.

Back

The mass of the gas increases causing density to increase & buoyancy to decrease.
