The density of liquid gallium at `30^(@)C` is 6.095 g/mL. Because of its wide liquid range (30 to `2400^(@)C`), gallium is used as a barometer fluid at high temperature. What height (in cm) of gallium will be observed on a day when the mercury barometer reads 740 torr? ` ` (The density of mercury is 13.6 g/mL.)
A
322
B
285
C
165
D
210

Barometer is constructed using liquid . What would be height of liquid column when mercury barometer reads 76cm
What is the barometric height of a liquid of density 3.4 g cm^(-3) at a place, where that for mercury barometer is 70 cm?
Determine height h of oil in the U tube as shown in fig. Density of oil =0.9 g//c c , Density of liquid is 1.6 g//c c and density of mercury. = 13.6 g//c .
The density of liquid mercury is 13.6 g//cm^(3). How many moles of mercury are there in 1 litre of the metal? (Atomic mass of Hg=200).
A monometer contains a liquid of density 5.44g//cm^(3) is attached to a flask containing gas A' as follows If the same liquid is used in barometer to measure the atmospheric pressure, then what will be the length of the liquid column, which exerts pressure equal to 1 atm ? (density of Hg = 13.6 g//cm^(3) )
Height of mercury in a barometer is h_0 = 76. 0 cm at a temperature of theta_1 = 20^(@)C . If the actual atmospheric pressure does not change, but the temperature of the air, and hence the temperature of the mercury and the tube rises to theta_(2)= 35^(@)C , what will be the height of mercury column in the barometer now? Coefficient of volume expansion of mercury and coefficient of linear expansion of glass are gamma_(Hg) =1.8xx10^(-4).^(@)C^(-1), alpha_(g)=0.09xx10^(-4).^(@)C^(-1)
