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:  \(ml\)
