$$ \Delta L = \alpha L_0 \Delta T $$

The mathematical relationship governing this phenomenon is given by the equation: However, many students struggle to apply the formula

| Mistake | Consequence | Correct Approach | |---------|-------------|------------------| | Using mm and m inconsistently | Factor of 1000 error | Convert all lengths to meters (or all to cm). | | Forgetting ΔT is in °C or K | Wrong value | ΔT in °C = ΔT in K. No 273 needed. | | Using α instead of β for volume | Wrong expansion | For volume: β = 3α (isotropic solids). | | Ignoring sign for contraction | Incorrect final length | If ΔT negative, ΔL negative. | | Stress sign conventions | False tension/compression | Expansion prevented → compression (negative strain). | $$ \Delta L = \alpha L_0 \Delta T
