Question

average atmospheric pressure at sea level is about...

select one:
a. 14.7 psi
b. 1.47 psi
c. 147 psi
d. 0.147 psi

Explanation:

Identify standard atmospheric pressure

Standard atmospheric pressure at sea level is defined as \(1\text{ atm}\).

Convert to pounds per square inch (psi)

The conversion factor from atmospheres to pounds per square inch is:

$$ 1\text{ atm} \approx 14.696\text{ psi} $$

Match with the given options

Rounding \(14.696\text{ psi}\) gives approximately \(14.7\text{ psi}\), which corresponds to option (a).

Answer:

• (a) 14.7 psi (Correct answer)
• (b) 1.47 psi
• (c) 147 psi
• (d) 0.147 psi
