Multiple Choice

One atmosphere is equal to 101.325 pascals.

Explanation:
Understanding atmospheric pressure in different units helps you see why this statement isn’t correct as written. One standard atmosphere is defined as 101,325 pascals. That means in kilopascals it is 101.325 kPa, and in other common units it is 760 millimeters of mercury (mmHg) or torr, or about 14.7 pounds per square inch (psi). So the correct way to express one atmosphere in pascals is 101,325 Pa, not 101.325 Pa.
