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 descends to 40 meters below the surface and has a 10 liter tank that contains air at 9 MPa and 7 C. Assume that the water has a density of 1000 kg/m3 and that atmospheric air is 100 kPa. He breathes at 5 liters/min. How long can he stay at the 40 meter depth? answer should be around 34.6 minutes

A SCUBA tank, an air tank used for breathing under water, is initially filled with gas at a pressure of 2.2x107 Pa and 24 oC. The tank has a volume of 16.0 L. If the tank will continue to provide air until it reaches a pressure of 2.2x106 Pa, how many moles of gas will it provide to a diver diving in water at 6 oC? Give your answer to at least three significant figures.
A diver has a compressed air tank that is initially at . The tank is connected to a regulator such that the diver is breathing in air at 760 mmHg. The diver breathes in 0.50 L of air each breath, and takes about 12 breaths per minute. The diver will need to surface when the tank pressure reaches . The tank is made of thick metal and does not change from initial volume of 11 L. Calculate the amount of...
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
a scuba diver tank contains 0.18 kg of O2 compressed into a volume of 4.0 L. calculate the gas pressure inside the tank at 15 degrees Celsius.
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.
(a) Calculate the absolute pressure at the bottom of a fresh-water lake at a depth of 25.8 m. Assume the density of the water is 1.00 ✕ 103 kg/m3 and the air above is at a pressure of 101.3 kPa. Pa (b) What force is exerted by the water on the window of an underwater vehicle at this depth if the window is circular and has a diameter of 36.0 cm? N
A compressed air tank carried by scuba divers has a volume of 9.5 L and a pressure of 140 atm at 20 °C. Part A What is the volume of air in the tank (in liters) at STP? Express your answer using two significant figures. IVO AQ R O 2 ? V =
A compressed air tank carried by scuba divers has a volume of 9.0 L and a pressure of 140 atm at 20∘C. If the gas was instead in a cylinder with a floating, massless, frictionless piston, what would the volume of the gas be (in liters) at STP? Express the volume in liters to two significant digits.
