The air space wouldĬ become 1/3 the size it was at the surface.ĭ become 2/3 the size it was at the surface.Ĭ A cold, allergy or another medical problem.Ī cold, or any congestion, can block air passages in your ears and sinuses, making equalization difficult or impossible. ✔Ans✔ 3) I turn a glass upside down, trap the air in it by putting it in water, and then I take the glass down to 10 meters. See Being a Diver I - Water Pressure and Air Volume Effects. An air volume taken to this depth from the surface would decrease and become half the size. What will happen to the balloon and the air inside it?Ī The balloon will get bigger and the air inside the balloon will be less dense (molecules move further apart).Ĭ The balloon will get bigger and the air inside the balloon will be more dense.ĭ The balloon will get smaller and the air inside the balloon will be less dense.Ī become half the size it was at the surface.Īt 10 meters, the pressure is 2 bar. ✔Ans✔ 2) I blow up a balloon, tie it off, and take it to the bottom of the swimming pool. The balloon would get smaller and the air density inside would be greater. This causes the density of the air inside to increase and air molecules are pushed closer together. ✔Ans✔ 1) If an object is neutrally buoyant (does not sink or float) in fresh water, the same object placed into salt water wouldī The balloon will get smaller and the air inside the balloon will be more dense (molecules move closer together).Īs water pressure increases, the volume of an air space will decrease. See Being a Diver I - Buoyancy and Controlling Buoyancy. An object that is neutrally buoyant in fresh water would float in salt water because there is greater upward force. Salt water is heavier than fresh water because it has dissolved minerals in it.
