Termal expansion is a fenomenon where metale change in sine when ne subied to temperatur variations. Understanding this behavor is essential for contexers and designaners to ensure thee safety and functionaty of metal contexts in various applications.

Basics of Thermal Expansion

When metale are e heated, their ir atoms vibrate more energy, causing the material to expand. Conversely, coloing results in contraction. The count of expansion depends on thee material 's conperties and the temperatur change.
