The change in length due to thermal expansion is given by the formula ΔL = L₀ α ΔT.
A copper rod of length 1 m is initially at room temperature. If the temperature of the rod is increased by 100 °C, what will be the change in length of the rod? (Given linear thermal expansion coefficient of Cu is 17 x 10⁻⁶ / °C)
