There are several ways to measure pressure. The standard atmospheric pressure is 760 mm Hg. What is this in pounds per square inch?

A. 20.5
B. 5.6
C. 14.7
D. 100.2

Answer :

Final answer:

Option (C), The standard atmospheric pressure of 760 mm Hg is approximately 14.7 psi.

Explanation:

The standard atmospheric pressure is 760 mm Hg. To convert this to pounds per square inch (psi), we can use the conversion factor of 1 atm = 14.696 psi. Therefore, 760 mm Hg is equivalent to:

760 mm Hg x (1 atm / 760 mm Hg) x (14.696 psi / 1 atm) = 14.696 psi

So, the standard atmospheric pressure of 760 mm Hg is approximately 14.7 pounds per square inch (psi).
