Example 9.10: Using the Combined Gas Law
When filled with air, a typical scuba tank with a volume of
13.2 L has a pressure of
153 atm (
Figure 16). If the water temperature is
27 °C, how many liters of air will such a tank provide to a diver’s lungs at a depth of approximately
70 feet in the ocean where the pressure is
3.13 atm?
