The fraction of the volume of a glass flask must be filled with mercury so that the volume of the empty space may be the same at all temperature is
`(alpha_("glass") = 9 xx 10^(-6)//^(0)C, gamma_(Hg) = 18.9 xx 10^(-5) // ^(0)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 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 glass beaker holds exactly 1 L "at" 0^@ C (a) What is its volume at 50^@ C ? (b) If the beaker is filled with mercury at 0^@ C , what volume of mercury overflows ehen the temperature is 50^@ C ? alpha _ g = 8.3 xx 10^-6 per ^@ C and gamma_Hg = 1.82 xx 10^-4 per ^@ C .

A glass beaker holds exactly 1 L "at" 0^@ C (a) What is its volume at 50^@ C ? (b) If the beaker is filled with mercury at 0^@ C , what volume of mercury overflows ehen the temperature is 50^@ C ? alpha _ g = 8.3 xx 10^-6 per ^@ C and gamma_Hg = 1.82 xx 10^-4 per ^@ C .

The internal volume of a glass flask is 540cm^(3) . What volume of mercury should be kept in the flask so that the volume of the empty space remains constant at any temperature? Real expansion of mercury =1.8 times 10^(-4@)C^(-1) and volume expansion of glass =2.5 times 10^(-5@)C^(-1).
