lämpölaajenemisien
Lämpölaajeneminen is the Finnish term for thermal expansion. It describes the tendency of matter to change its volume, area, or length in response to a change in temperature. When a substance is heated, its constituent particles gain kinetic energy and move more vigorously. This increased motion causes them to spread further apart, resulting in an overall increase in the size of the substance. Conversely, when a substance is cooled, its particles lose kinetic energy, move less, and the substance contracts.
The extent of thermal expansion varies depending on the material and the temperature change. Different substances
Understanding thermal expansion is crucial in many engineering and scientific applications. For instance, bridges are often
