A Cаrtesiаn diver cаn be created tо shоw the relatiоnship between the pressure and volume of a gas. In this experiment, a small tube filled with air (the diver) is suspended in a large pop bottle filled with water. When the pop bottle is squeezed, the volume of air inside the eyedropper changes, and the “diver” moves down in the bottle as shown in the following diagram. To get the “diver” to drop, the volume of trapped air must be decreased by 50 %. If the initial pressure exerted by the water were 98.0 kPa, the bottle should be squeezed so that the pressure exerted by the water would be (hint: Boyle’s Law)
