Question

What is real and apparent expansion of liquids

Jyoti Pant · Accepted Answer

When a liquid kept in a container is heated,there is an
expansion of container along with the liquid But the amount of
expansion of container is small than that of liquid When the
expansion of liquid is considered ignoring the expansion of the
container is called apparent expansion The real expansion is
calculated by adding the expansion of the part of the container
containing liquid before expansion with the apparent expansion of
liquid
