If mercury and glass had equal coefficient of volume expansion, could we make a mercury thermometer in a glass tube?

The glass with smallest coefficient of expansion of

A piece of metal floats on mercury. The coefficients of volume expansion of the metal and mercury are gamma_1 and gamma_2 respectively. If the temperatures of both mercury and the metal are increased by an amount DeltaT , the fraction of the volume of the metal submerged in mercury changes by the factor............

A piece of metal floats on mercury. The coefficient of volume expansion of metal and mercury are gamma_1 and gamma_2 , respectively. if the temperature of both mercury and metal are increased by an amount Delta T , by what factor does the frection of the volume of the metal submerged in mercury changes ?

The remaining volume of a glass vessel is constant at all temperature if (1)/(x) of its volume is filled with mercury. The coefficient of volume expansion of mercury is 7 times that of glass. The value of x should be

Mercury does not cling to glass. Why?

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

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 flask of mercury is sealed off at 20^@C and is completely filled with mercury. If the bulk modulus for mercury is 250 Mpa and the coefficient of volume expansion of mercury is 1.82xx10^(-4)//^(@)C and the expansion of glass is ignored, the pressure of mercury within flask at 100^@C will be
