Pressure outside air space is more than pressure inside air space. How do you maintain air volume as you descend? Equalize What is a "squeeze"? As volume decreases, pressure pushes body tissues inwards toward air space, causing discomfort. 1 bar is what depth? 0m/0ft 2 bar is what depth? 33ft/10m 3 bar is what depth? 66ft/20m 4 bar is what depth? 99ft/30m How is air volume affected when depth is increased? It decreases How is air density affected when depth is increased? It increases What happens if you take an air volume underwater with you in a flexible container or inverted jar? As pressure increases the volume decreases, same air but smaller space.
Where are some air spaces located in the body? Ears, sinuses, lungs Do you always feel the pressure in body air spaces? Only if the pressure is different inside and outside the air spaces.
