A steel scuba tank contains compressed air at 2250 psi. What is
the pressure expressed in atmospheres?
A) 29.6 atm
B) 153 atm
C) 75.3 atm
D) 3.31 × 104 atm
E) 2.96 atm
A steel scuba tank contains compressed air at 2250 psi. The pressure expressed in atmospheres.
Answer :- (B) 153 atm
Since,
1 psi =0.068 atm
psi = pound-force per square inch

A scuba diver 40 ft below the ocean surface inhales 55.0 mL of compressed air from a scuba tank at a pressure of 3.20 atm and a temperature of 7 ∘C. What is the final pressure of the air, in atmospheres, in the lungs when the gas expands to 155.0 mL at a body temperature of 37 ∘C, and the amount of gas does not change?
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 scuba diver's tank contains 0.29 kg of O2 compressed into a volume of 2.3 L. 1. Calculate the gas pressure inside the tank at 7 C. Express your answer using two significant figures in atm 2. What volume would this oxygen occupy at 25 C and 0.97 atm? Express your answer using two significant figures in Liters
12) A scuba tank contains an air at 300 kPa and 600 K. Half of the air is withdrawn from the tank leaving the tank at a pressure of 100 kPa. Assuming no heat transfer, what is the temperature of the gas when the process is complete? (a) 100 K (b) 200 K (c) 300 K (d) 400 K (e) 500 K 13) A 0.6875 cubic meter rigid tank contains 0.5 kg of steam at 0.4 Mpa. The steam is...

A scuba tank is filled with air to a gauge pressure of 204 atm when the air temperature is 33 ∘C. A diver then jumps into the ocean and, after a short time on the ocean surface, checks the tank's gauge pressure and finds that it is only 196 atm. Assuming the diver has inhaled a negligible amount of air from the tank, what is the temperature of the ocean water? Express your answer to two significant figures and include...
A scuba tank is filled with air to a gauge pressure of 203 atm when the air temperature is 34 ∘C. A diver then jumps into the ocean and, after a short time on the ocean surface, checks the tank's gauge pressure and finds that it is only 196 atm. (A) Assuming the diver has inhaled a negligible amount of air from the tank, what is the temperature of the ocean water? Express your answer to two significant figures and...
8. If you have a 3.0 L cylinder of compressed air that contains 2.0 g of O2, and 8.0 g of N2, then at room temperature (assume 298 K), what would be the total pressure in the tank (in atm), and the pressures of O2, and of N2 (also in atm) separately? 1. A guage on a compressed gas cylinder in a hospital reads 2.200 E3 psi (pounds per square inch). (1.00 atm = 14.7 psi). Express this pressure in...
Process Design & Control Consider the process of filling a tank with compressed air from a constant pressure supply. Consider the process of filling a tank with compressed air from a constant pressure supply The tank has a volume of 500 ft' and initially is at atmospheric pressure and 75°F. The tank is connected to a high pressure air line that contains a control valve. The valve is quickly opened when the filling process begins, and the flow rate of...
A scuba diver’s tank contains 0.29 kg of O2 compressed into a volume of 2.3L a) What volume would this oxygen gas occupy at 26 °C and 96.3 kPa? b) Using the definitions for density and Molecular Weight, what is the density 9 in g/L) of dioxygen gas at 77 °C and 700.0 torr?
