Question

Quizplus · Accepted Answer

The average pressure of the atmosphere at sea level is 760 mm Hg (millimeters of mercury). This is also equivalent to 1 atmosphere or 101.3 kPa (kilopascals). Choice B is incorrect because it gives the pressure in inches of mercury, which is not the standard unit for atmospheric pressure. Choice C is also correct, as torr is another unit of pressure that is equivalent to mm Hg. However, choice D is incorrect as bars are a much larger unit of pressure and not used for atmospheric pressure.
