Understanding Thermal Expansion

Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature. The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. This calculator specifically finds the linear expansion, which is the change in one dimension (length) as opposed to area or volume.

Formula Used: `ΔL = α × L₀ × ΔT`, where `ΔL` is the change in length, `α` is the coefficient of thermal expansion, `L₀` is the initial length, and `ΔT` is the change in temperature.
