Coefficient Of Expansion (Noun)
Meaning
The fractional change in length or area or volume per unit change in temperature at a given constant pressure.
Classification
Nouns denoting quantities and units of measure.
Examples
- The coefficient of expansion of a material determines how much it will expand or contract in response to a given change in temperature.
- The laboratory tested the coefficient of expansion of various metals to compare their thermal properties.
- A high coefficient of expansion means that the material will change size significantly with even a small change in temperature.
- Engineers often need to consider the coefficient of expansion when designing components that will be exposed to large temperature fluctuations.
- The coefficient of expansion is an important factor in the design of bridges and other structures that may be subject to large variations in temperature.
