Explanation:
For liquids, two types of thermal expansion coefficients are defined:
- Real (True) Expansion Coefficient – Refers to the actual expansion of the liquid itself.
- Apparent Expansion Coefficient – Refers to the observed expansion when the liquid is in a container, since the container also expands.
