lämpömuodonmuutos
Lämpömuodonmuutos, also known as thermal expansion, is the tendency of matter to change its volume in response to changes in temperature. When heated, the atoms and molecules within a substance gain kinetic energy and vibrate more vigorously, causing them to spread further apart. This increased spacing leads to an overall expansion of the material. Conversely, when a substance cools, its particles lose kinetic energy, move less, and come closer together, resulting in contraction.
This phenomenon is observed in all states of matter: solids, liquids, and gases. Solids generally expand less
Understanding lämpömuodonmuutos is crucial in many engineering and scientific applications. For instance, it must be accounted
