Question

Apparent expansion of the liquid is its expansion relative to the _______

Answer 1

A liquid is heated in a container. Heat flows through the container to the liquid. It 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. We cannot observe the intermediate state. We can only observe the initial and the final levels. This observed expansion of the liquid is known as the apparent expansion of the liquid.
