a bottle of alluminium (1L ) at 20 C is filled to the top with mercury. The bottle is then heated to 110 C.

How much mercury will spill?  

Solutions

Expert Solution

Important constants needed for the calculation :

Coefficient of linear expansion of aluminium

Coefficient of volume expansion of aluminium bottle,

Coefficient of volume expansion of Mercury,

Given that :

Volume of the aluminium bottle (V) = 1 L

Initial temperature (Ti) = 20°C

Final temperature (Tf) = 110°C

Temperature difference, = 110 - 20 = 90°C

Solution :

Increase in volume of Mercury =

= 0.0162 L

Increase in the volume of Al bottle =

= 0.00621 L

Amount of Mercury spilled out is the difference between volume increased in Mercury and volume increased in bottle

ie, Volume of Mercury spilled = 0.0162 - 0.00621

= 0.00999 L Hg

By converting into mL,

Volume of Mercury spilled out = 9.99 mL

A container is filled to the brim with 1.4 L of mercury at 20°C. As the temperature of the container and mercury is increased to 51°C, a total of 7.6 mL of mercury spill over the brim of the container. Determine the linear expansion coefficient of the material that makes up the container. The coefficient of volume expansion of mercury is 1.8☓10-4 (°C)-1.
