A manometer is connected to a gas containing bulb. The open and reads 43.7 cm whereas the arm connected to the bulbs read 15.6 cm. if the barometic pressure is 743 mm mercury, what is the pressure of the gas in bar?

Text Solution

Verified by Experts

Excess pressure of the gas =43.7-15.6=28.1 cm =281mm . Total pressure of the gas 743+281+1024 mm Now 1 atm =1.01325 bar = 1 bar 1024 mm pressure =1024

An open-end manometer was used to determine the pressure of a gas present in a container. It was found that the height of mercury level in the arm attached to the gas-filled container was 4 cm higher than that in the open ene arm. If the atmospheric pressure was measured to be 76 cm Hg, then what will be the pressure of the gas inside the container in atm unit?

A bulb filled with a gas is connected to an open -end manometer. the level of mercury in the arm attached to the gas bulb is 20 cm lower than that in the open. end arm, calculate the pressure of the gas in the bulb in the units of atm and Pa? Consider the atmospheric pressure to be 76 cm Hg.

Two bulbs of equal volume are connected by a narrow tube of negligible volume and filled with a gas at STP. IF one of the bulbs is kept in melting ice and the other in the water bath at 62^@C ,what will be the new pressure of the gas?
