The three types of thermal expansion are:
- Linear Expansion
- Expansion that occurs in one dimension (length).
- Example: A metal rod lengthening when heated.
- Area Expansion
- Expansion in two dimensions (length and width).
- Example: The surface area of a metal sheet increasing with temperature.
- Volume Expansion
- Expansion in three dimensions (length, width, and height).
- Example: A heated gas or liquid expanding in all directions inside a container.
