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

`(3V)/(40)`

`(V)/(20)`

`(3V)/(20)`

`(V)/(30)`

Text Solution

Verified by Experts

The correct Answer is:

`gamma_(Hg) = 20alpha_(s) , V_(Hg)gamma_(Hg) = V_(Hg)gamma_(Hg) = V_(g)gamma_(g)`

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:
