Real expansion of liquid = Apparent expansion of liquid + Volume expansion of container. Type 1 for true and 0 for false

Open in App

Solution

If it had been possible to heat a liquid without keeping it in a vessel then the real expansion of the liquid that would be obtained is called real expansion of the liquid but heating a liquid without a container is not possible. So considering the expansion of the container the actual expansion of the liquid that is obtained is called the real expansion.

Apparent expansion: The expansion of liquid apparently observed without considering the expansion of the container is called the apparent expansion of liquid. Apparent expansion of liquid is less than its actual expansion.

Real expansion of liquid $=$ Apparent expansion of liquid $+$ Volume expansion of container.
