What volume will 250 g of mercury occupy ? (Density of mercury =13.6 g `cm^(-3)`)

The volume of an air bubble becomes 8 times the original volume in rising from the bottom of a lake to its surface. If the barometice height is 0.76 m of mercury (density of mercury is 13.6 g cm^(-3) and g = 9.8 ms^(-2)) what is the depth of the lake ?

A vertical U-tube of uniform inner cross section contains mercury in both sides of its arms. A glycerin (density =1.3 g//cm ^(3)) column of length 10 cm is introduced into one of its arms. Oil of density 0.8 gm //cm^(3) is poured into the other arm until the upper surfaces of the oil and glycerin are in the same horizontal level. Find the length of the same horizontal level. Find the length of the oil column, Density of mercury =13.6 g//cm^(3)

A cube floating on mercry has 1/4 of its volume will remain immresed in mercury? (Relative density of mercury =13.6)

A barometer kept in an alevator ac celerating upward reads 76 cm of mrecury. If the elevator is ac celerating upwards at 4.5ms^(-2) find the air pressure in the elevator in cm of mercury. Density of mercuty =13.6 xx 10^3 kg m^(-3) G = 9.8 m//s^2

Convert a pressure of 76 cm of mercury into Nm^(-2) . Density of mercury is 13.6 gm//c c .

Caculate the root mean square velcity of molecules of a gas whose densilty is 1.4kgm^(-3) at a pressure of 76cm of mercury (sp. gr. sp.of mercury =13.6 and g=9.81ms^(-2) )
