## Definition

Stands for Coefficient of Thermal Expansion. A number that shows how much a material expands or contracts when the temperature changes. It helps engineers choose the right materials for things like bridges and pipes.

For teachers: Abbreviation for Coefficient of Thermal Expansion. A material property that quantifies the fractional change in size per unit change in temperature. It is essential for calculating dimensional changes in engineering and construction.

## Examples

- Steel has a lower CTE than aluminum.
- Engineers must account for the CTE of the materials when designing a bridge to prevent cracks during extreme weather.
- The mismatch in the CTE between the silicon chip and the ceramic substrate caused significant thermal stress during the soldering process, leading to micro-cracks in the final assembly.
