The correct answer is: The balloon will expand to twice its size and the density of the air will decrease by half. So the balloon filled with air will expand at the surface and the density of the air will decrease. The density is greater at depth, but will decrease when it goes up. Inversely, at the surface the air volume will increase by 2 times, expanding the balloon. This means that the volume of air in the balloon at 2 ata is decreased by 2 times would it would be at the surface. In this case, we start at 10 meters/33 feet, or 2 ata. This comes into effect when calculating air consumption. What does this mean? When calculating densities you divide when you go up and multiply when you go down. With Density it’s all the other way around because as you squash the gas the deeper you go and make its volume smaller you increase its density – if the gas expands (when going up) then you decrease its density.
Boyle’s Law states that the volume of a gas is inversely proportional to the surrounding pressure on the gas. Answer: B Feedback: For all intents and purposes you cannot compress a liquid or a solid by applying greater pressure, but you can compress a gas as the molecules are further apart. The balloon will expand to twice its size and the air density will increase by a factor of 2. The balloon will shrink to half its original size and the density of the air will increase by a factor of 2. The balloon will expand to twice its size and the density of the air will decrease by half. The balloon will shrink to half its original size and the density of the air will decrease by half. FALSE Answer: B 2.What would happen to a balloon that is filled with air at 10meters/33 feet if you bring it to the surface? A. 1.Nitrogen narcosis most commonly happens at a depth of 18 meters/60 feet.
