Question

A container of capacity 70ml is filled with a liquid up to 50ml. when it is heated the liquid level falls to 48.5ml and then rises to 51.2ml . find the apparent and real expansion ​

Answer 1

Explanation:

Level of the liquid L1 = 50 ml

Level of the liquid L2 = 48.5 ml

Level of the liquid L3 = 51.2 ml

Apparent expansion = L3 − L1

= 51.2 ml – 50 ml = 1.2ml

Real expansion = L3 − L1

= 51.2 ml – 48.5ml = 2.7ml

So, Real expansion > apparent expansion
