| Coeficiente de expansión lineal | |
The Coefficient of Thermal Expansion is the rate change in the size of an object with the rate change in the temperature. It generally measures the fractional change in the size of the object with the change in the temperature keeping the pressure constant. There are several types of thermal coefficients that are developed such as linear, volumetric and area thermal coefficients Changes in length compared to the original length (Δℓ / ℓ0) called linear expansion |  |
