Question
How does the level of liquid in a container change on heating the liquid of cubical expansion in the container having coefficient of linear expansion α/3?
Solution
The coefficient of linear expansion of container is 
/3. Therefore, coefficient of cubical expansion of container is equal to coefficient of cubical expansion of liquid.
Hence, the level of liquid in container will neither rise nor fall.
