A container whose capacity is 70 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 51.2 ml. find the apparent and real expansion.

Explanation

Level of the liquid `L_(1)=50 ml`
Level of the liquid `L_(2)-48.5 ml`
Level of the liquid `L_(3)=51.2 ml`
Apparent expansion `L_(3)=L_(1)=51.2 ml-50 ml=1.2 ml`
Real expansion `=L_(3)-L_(1)=51.2 ml-48.5 ml=2.7 ml`
So, Real expansion > apparent expansion
