Question

the ocean pressure at the depth of the titanic wreck is 400. atm. calculate the ocean pressure in kpa. round answer to 3 significant digits.

Explanation:

Step1: Recall the conversion factor

We know that \(1\space \text{atm} = 101.325\space \text{kPa}\).

Step2: Multiply the given pressure in atm by the conversion factor

The pressure is \(400\space \text{atm}\). So we calculate \(400\times101.325\).
\[400\times101.325 = 40530\]

Step3: Round to 3 significant digits

\(40530\) rounded to 3 significant digits is \(4.05\times 10^{4}\) (or \(40500\) when written in standard form, but in scientific notation for 3 significant digits it's \(4.05\times 10^{4}\)).

Answer:

\(4.05\times 10^{4}\) (or \(40500\)) kPa
