18. Problem to find the real and apparent expansion in liquids

A container whose capacity is 85 $ml$ is filled with a liquid up to 50 $ml$. Then, the liquid in the container is heated. Initially, the level of the liquid falls from  50 $ml$ to 48.5 $ml$. Then we heat more, the level of the liquid rises to 51 $ml$

 

Find the apparent and real expansion.

 

  

Apparent Expansion:  \(ml\)

  

Real Expansion:  \(ml\)
