A SCUBA tank can normally hold 18 L of gas at 3000 psi. How many liters of gas would this be equivalent to if the gas were at 14.7 PSI?

Answer:

  • 4,000 liters

Explanation:

Assume constant temperature and use Boyle's law:

          [tex]PV=constant\\\\P_1V_1=P_2V_2\\\\3,000psi\times 18L=14.7psi\times V_2\\\\V_2=3,000psi\times 18L/14.7psi\\\\V_2=3,673.47L[/tex]

You must reound to one significant figure because 3,000 psi has one significant figure.

           [tex]V_2=4,000L[/tex]
