Answer 1

Answer #1

Pressure,

P = density * g* height

Where g is acceleration due to gravity.

Since pressure is same for both,

density(mercury)*g*h(mercury) = density(water)*g*h(water)

density(mercury)*h(mercury) = density(water)*h(water)

13.5 g/cm^3 * 751 mm = 1.00 g/cm^3 * h(water)

h(water) = 10138 mm

h(water) = 1013.8 cm

Answer: 1.01*10^3 cm

In principle many different liquids could be used in a barometer. Mercury is usually preferred by virtue of its low vapour pressure and high density. As part of a school project, you have decided to build a barometer using water. Assuming the maximum pressure that the instrument will need to read is 1.05 atm, determine the height of the column required if (a) you ignore the vapour pressure of water or (b) you take the vapour pressure of water (PH2O=3.17...
