4. A glass vessel contains tungsten balls and is filled with mercury to a certain mark. It is found that the mercury level always remains at this
mark when the glass vessel is heated. What is the ratio of volume of Hg
to that of tungsten at 0°C. (linear expansivity of glass= 8 x 10^-6 /°C , cubical expansivity of mercury
18 x
10^-5 /°C and linear expansivity of tungsten= 4.4 x 10^-6 /°C)
