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.
