When a cylinder is subjected to temperature changes, it undergoes thermal expansion. As the temperature increases, the cylinder’s molecules gain energy, causing them to move apart, resulting in an increase in its volume and length. Conversely, when the temperature decreases, the cylinder contracts, reducing its volume and length. This expansion and contraction phenomenon is governed by the coefficient of thermal expansion, which varies with different materials.
