The weather news gives the atmospheric pressure as 1.07 atm. What is this atmospheric pressure in mm Hg?
 A 812.3 mmHg B 81.32 mmHg C 81.23 mmHg D 813.2 mmHg
Explanation:

Detailed explanation-1: -Atmospheric pressure is measured by a barometer and barometer’s height at normal temperature and pressure at sea level is 76 cm of Hg or 760 mm of mercury, which represents 1 atm.

Detailed explanation-2: -One atm. equals 760.0 mm Hg, so there will be a multiplication or division based on the direction of the change. Example #1: Convert 0.875 atm to mmHg. Solution: multiply the atm value by 760.0 mmHg / atm.

Detailed explanation-3: -Normal is 29.9; range  29.6-30.2 inches Hg (752-767 mm Hg)… at SEA LEVEL! Rarely (at sea level) do readings exceed 30.4 inches Hg (773 mm Hg)…

Detailed explanation-4: -One atmosphere is 1, 013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases.
