Automatic bleeding of sinuses / the inability to equalize airspacesī. Carotid Sinus reflex results in _ primarily caused by _.Ī. Refraction / Light travels at different speed underwaterġ. Under certain conditions, underwater objects appear to be further away than it actually is this phenomenon is known as _ and it is primarily caused by _.Ĭ.

Cannot be determined with the information givenġ2. What is the exact volume of this object?ĭ. An object weighing 67kg is negatively buoyant in fresh water and neutrally buoyant in salt water. Unable to determine with the information givenġ1. An object that is positively buoyant in salt water would _ in fresh water.ī. When the pressure of a gas is increased while it is still in contact with a liquid:ġ0. What is the partial pressure of nitrogen and oxygen in this tank when breathed at 29m in freshwater?ĩ. A scuba tank is filled with 35% of oxygen and 65% of nitrogen. Volume 36 liters and density 3 times greater.Ĩ. Volume – 12 liters and density 3 times greater.ĭ. Volume – 24 liters and density are 2 times greater.Ĭ. Volume – 12 liters and density unchanged.ī. What is the new volume and what will happen to the density inside the container upon Reaching 20m?Ī. A sealed metal container with a volume of 12 liters is taken down into seawater. What is the absolute pressure at 27m of fresh water?ħ. How much air do you need to add to your lifting device to move it off the bottom?Ħ.

A huge anchor weighing 645kg lies at 23m at the bottom of the sea. A diver breathing compressed air from a scuba tank that contains 0.75% of Carbon Monoxide at 45m in seawater would have the same effect as a person breathing what Percent of Carbon Monoxide at the surface?ĥ. Pressure within the tank increases and volume is unchanged.Ĥ. Volume increases and pressure within the tank is unchanged.ĭ. Pressure within the tank decreases and volume is unchanged.Ĭ. Volume decreases and pressure within the tank increases.ī. What will happen if this tank is then placed in an environment near 40 degrees Celsius?Ī. A scuba tank is filled with an ambient pressure of 10 degrees Celsius. Sound travels _ times faster underwater making it difficult for divers to determine the _ of it.ģ. Water has the capability to _ light because of this _ color disappearing first underwater.Ģ.
