If a scuba diver goes down 55 m, how many atm is she experiencing?
Answer Sheet:
Every 10 meters adds one atm pressure. So if you are 10 meters down, the pressure is 2 atm.
So For 55meters down the pressure the pressure is = 1atm + 5.5 atm = 6.5 atm
So she is experiencing 6.5 atm pressure .
A scuba diver is at a depth of 445 m, where the pressure is 45.5 atm. What should be the mole fraction of O2 in the gas mixture the diver breathes in order to have the same partial pressure of oxygen in his lungs as he would at sea level? Note that the mole fraction of oxygen at sea level is 0.209.
A scuba diver exhales 3.32 L of air while swimming at a depth of 20.0 m where the sum of atmospheric and water pressure is 2.95 atm. By the time the bubbles of air rise to the surface, where the pressure is 1.00 atm, what is their total volume? Assume the temperature of the water body is uniform.
4) A scuba diver is searching for a sunken ship off the coast of NC. She is submerged in seawater 30 m below the water surface Her total volume, including her gear, is 65.0L and her total mass is 68.0 kg1.025 x 103kg/ m2. S A) Calculate the total volume of the submerged diver in cm2 and m. Volume of diver- mJ B) List an object that has a similar volume to the diver. Be creative and try to visualize...
A scuba diver releases a balloon containing 181.8 L of helium attached to a tray of artifacts at an underwater archeological site. When the balloon reaches the surface it has expanded to 478.5 L. The pressure at the surface is 1.098 atm. Pressure increases by 1.0 atm for every 10 m of depth. At what depth was the diver working? Assume the temperature of the helium is constant. Type your response in m to the nearest tenth of a m.
A scuba diver creates a spherical bubble with a radius of 2.0 cm at a depth of 30.0 m where the total pressure (including atmospheric pressure) is 4.00 atm. What is the radius of the bubble when it reaches the surface of the water? (Assume atmospheric pressure to be 1.00 atm and the temperature to be 298 K.)
A scuba diver whose 12L tank is filled with air at a pressure of 150atm at a depth of 15m where the water pressure is 2.5atm. If she uses 30L of air per minute, the same pressure as the water pressure, how long can she stay at that depth? Please show work
Exercise 5.85 Part A A scuba diver creates a spherical bubble with a radius of 2.5 cm at a depth of 30.0 m where the total pressure (including atmospheric pressure) is 4.00 atm What is the radius of the bubble when it reaches the surface of the water?

9. A scuba diver is in fresh water has an air tank with a volume of 0.0100 m3. The air in the tank is initially at a pressure of 1.00 × 107 Pa. Assume that the diver breathes 0.500 L/s of air. Density of fresh water is 1.00 × 103 kg/m3. How long will the air in the tank last at 17.4 m? Answer is in min
A scuba diver is 45 m below the surface of a lake, where the
temperature is 5°C. He releases an air bubble with a volume of 10
cm3. The bubble rises to the surface, where the
temperature is 25°C. Assume that the air in the bubble is always in
thermal equilibrium with the surrounding water, and assume that
there is no exchange of molecules between the bubble and the
surrounding water. What is the volume of the bubble right before...
A scuba diver at a depth of 34.0 m below the surface of the sea off the shores of Panama City, where the temperature is 5.0°C, releases an air bubble with volume 15.0 cm3. The bubble rises to the surface where the temperature is 19.0°C. What is the volume of the bubble immediately before it breaks the surface? The specific gravity for seawater is 1.025.
