Staff will ensure that the tank pressure of SCBAs reads between _______ PSI and full.

a. 2000 PSI
b. 2500 PSI
c. 3000 PSI
d. 3500 PSI

Answer :

Final answer:

The correct answer is c) 3000 PSI. To convert a pressure of 3000 psi to other units, 3000 psi is approximately 204.138 atm and 155,144.7 mm of Hg.

Explanation:

The correct answer is c) 3000 PSI. A scuba diver begins diving at 3000 psi. To convert this pressure into atmospheres (atm) and millimeters of mercury (mm of Hg), we can use the following conversions:

1 psi = 0.068046 atmospheres

1 psi = 51.7149 mm of Hg

To convert 3000 psi to atm:

3000 psi imes 0.068046 atm/psi = 204.138 atm

To convert 3000 psi to mm of Hg:

3000 psi imes 51.7149 mm of Hg/psi = 155,144.7 mm of Hg.
