Calculate Coefficient of Thermal Expansion







Formula

The formula to calculate the Coefficient of Thermal Expansion is:

\[ \alpha = \frac{L_2 - L_1}{T_2 - T_1} \]

Where:

What is the Coefficient of Thermal Expansion?

The coefficient of thermal expansion is a numerical value that quantifies how much a material expands or contracts when its temperature changes. It represents the fractional change in length, area, or volume of a material per unit change in temperature.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \alpha = \frac{1.002 - 1.0}{100 - 20} \approx 2.50 \times 10^{-5} \, \text{1/°C} \]

The Coefficient of Thermal Expansion is approximately \(2.50 \times 10^{-5} \, \text{1/°C}\).
