A vertical glass tube,closed at the bottom contains mercury to a height of 100cm at `30^(@)C` , The height of mercury column at `50^(@)C` is `(gamma for Hg=1.8times10^(-4)/^(@)C`,`alpha_(g)=8times10^(-6)/^(@)C)`

A long horizontal glass capillary tube open at both ends contains a mercury thread 1 m long at 0^@C . Find the length of the mercury thread, as read on this scale, at 100^@C .

The height of the mercury column in a barometer provided with a brass scale corrercted at 0^(0)C is observed to be 74.9 cm at 15^(0)C . Find the true height of the column at 0^(0)C . alpha_(b) = 20 xx 10^(-6 //0)C and gamma_(Hg) = 175 xx 10^(-6 //^(0)C)

A glass flask of volume 200cm^(3) is just filled with mercury at 20^(@)C . The amount of mercury that will overflow when the temperature of the system is raised to 100^(@)C is (gamma_(glass)=1.2xx10^(-5)//C^(@),gamma_(mercury)=1.8xx10^(-4)//C^(@))

A flask is filled with mercury at temperature 28^(@)C . If the flask and the contents are heated to 48^(@)C , the volume of mercury above the mark will be (alpha_(glass=9xx10^(-6)//^(@)C , gamma_(Hg)=180xx10^(-6)//^(@)C)

A one litre flask contains some mercury. It is found that at different temperatures the volume of air inside the flask remains the same. The volume of mercury in the flask is (alpha_(glass)=9xx10^(-6)//^(@)C,gamma_(Hg)=180xx10^(-6)//^(@)C)

A brass sheet is 25 cm long and 8 cm breath at 0^(@) C . Its area at 100^(@)C is (alpha = 18 xx 10^(-6 // ^(@))C)

The brass scale of a barometer gives correct reading at 10^(@)C . The baometer reads 75 cm at 30^(@)C . What is the a atmoshpheric pressure at o^(@)C ("in cm "Hg) (alpha_("brass")=20xx10^(-6)//^(0)C,lambda_(Hg)=175xx10^(-6)//^(@)C)

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)

A weight thermometer contains 51 g of mercury at 20^(0)C and 50g of mercury at 100^(0)C . The coefficient of apparent expansion of mercury in glass vessel is
