Thermal expansion is the increase in the volume of a substance when its temperature rises. This occurs because particles move faster and spread apart as they gain kinetic energy.
Thermal expansion refers to the tendency of a substance to increase in volume as its temperature rises. When a material is heated, its particles move faster and spread further apart, leading to an expansion of the substance. This phenomenon is observed in solids, liquids, and gases, though the degree of expansion varies. Thermal expansion has practical implications in engineering, construction, and daily life, as materials need to account for temperature changes. For example, bridges and railways include expansion joints to accommodate the expansion and contraction caused by temperature fluctuations.
