Question

Differentiate between Apparent expansion and Real expansion of liquids.​

Answer 1

This means that the container expands first, due to which the level of the liquid falls. When the liquid gets heated, it expands more and beyond its original level. ... This observed expansion of the liquid is known as the apparent expansion of the liquid and is less than its actual expansion.

Answer 2

Apparent Expansion means the thermal expansion of a liquid as measured in a graduated container without allowance for the expansion of the container.

The real expansion of the liquid = Apparent expansion of the liquid + Volume expansion of the container.
