the coefficient of volume expansion of mercury is `20`times the linear expansion of glass. Find the volume of mercury that must be poured in to glass vessel of volume `V` so that the volume above the mercury remain constant at all temperatures

The coefficient of real expansion of mercury is gamma and the coefficient of linear expansion of glass is alpha . The mercury thread, enclosed in a glass tube of uniform bore, expands linearly due to rise in temperature. The effective coefficient of expansion will be

In a cylidrical glass container a solid silica is placed vertically at its bottom and remaining space is filled with mercury upto the top level of the silica. The volume of silica remains unchanged with variation in temperature. The coefficient of cubical expansion of mercury is gamma and coefficient of linear expansion of glass is alpha . If the top surface of silica and mercury level remain at the same level wiht the variation in temperature then the ratio of volume of silica tothe volume of mercury is equal:

The linear expansivity of glass is 8xx10^(-6)K^(-1) and cubical expansivity of mercury is 18xx10^(-5)K . What volume of mercury must be placed inside a flask of 300cc, so that the volume of the flask not occupied by mercury may remain the same all temperature?

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

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

The volume expansion coefficients of glass and mercury are 2.4 times 10^(-5@)C^(-1) " and " 1.8 times 10^(-4@)C^(-1) respectively. What volume of mercury should be kept in the flask so that the volume of the empty space over mercury in the flask remains constant at all temperatures?

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............
