A one litre flask contains some mercury. It is found that at different temperature the volume of air inside the flask *** the same. What is the volume of mercury in flask ? Given that the coefficient of linear expansion of glass = 9 × 10–6(C)–1 and coefficient of volume expansion of mercury = 1.8 × 10–4 (C–1).
Let V = Volume of the vessel
V' = Volume of mercury
For unoccupied volume to remain constant increase in volume of mercury should be equal to increase in volume of vessel.
