lämpölaajenemisena
Lämpölaajeneminen refers to the phenomenon where matter generally expands when heated and contracts when cooled. This occurs because the average kinetic energy of atoms and molecules within a substance increases with temperature, causing them to vibrate more vigorously and move further apart. Conversely, as temperature decreases, the kinetic energy reduces, leading to less movement and a closer packing of particles.
The extent of thermal expansion varies significantly between different materials. Solids, liquids, and gases all exhibit
The linear expansion of solids, where the change in length is considered, is often described by the
Understanding lämpölaajeneminen is essential in many engineering and scientific applications, such as the design of bridges,
