Question

Explain the real and apparent expansions of liquids

Answer 1

A. Real expansion:

1. The expansion we see when a liquid is heated without a container is known as true expansion.
2. The expansion of liquid that is perceived without taking into account the expansion of the container is known as apparent expansion.
3. A liquid's real expansion is always larger than its apparent expansion.
4. unit of real expansion is “per kelvin”

B. Apparent expansion:

1. If you heat the liquid directly using a container, the expansion you see is called a apparent expansion of the liquid.
2. The apparent expansion of the liquid is the expansion of the liquid that is perceived by taking into account the expansion of the container.
3. Its SI unit is “per kelvin”
