Question

The height of the mercury in a barometer is directly proportional to the pressure on the mercury’s surface. At sea level, pressure averages 1.0 atm and the level of mercury in the barometer is 760 mm (30. in.). In a hurricane, the barometric reading may fall to as low as 28 in.

_________a. Convert a pressure reading of 28 in. to atmospheres.

_________b. What is the barometer reading, in mm Hg, at a pressure of 0.50 atm?

1 of 3

a) 1 inHg=0.033 atm1\ \mathrm{inHg}=0.033\ \mathrm{atm}

Multiply the given height of the mercury in the barometer in a hurricane with 0.033 to get the pressure in atm:

p=280.033 atm\mathrm{p}=28\cdot 0.033\ \mathrm{atm}

p=0.926 atm\mathrm{p}=0.926\ \mathrm{atm}
