Solution

Liquid always has to be heated keeping it in a container. The liquid, as well as the container, expand when the heat is applied.

This means that the container expands first, due to which the level of the liquid falls. So, the expansion of liquids observed by us is not the real expansion but it is an apparent expansion.
