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 takes a 2.3 L balloon from the surface, where the pressure is 1.0 atm and the temperature is 35 ∘C, to a depth of 30 m , where the pressure is 4.0 atm and the temperature is 17 ∘C. What is the volume of the balloon at this depth?
A scuba diver creates a spherical bubble with a radius of 3.5 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? (Assume atmospheric pressure to be 1.00 atm and the temperature to be 298 K.) Express your answer using two significant figures.
A scuba diver releases a balloon containing 115.0 L of helium attached to a tray of artifacts at an underwater archaeological site (see photo).

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
