Science > Physics > Thermal Properties of Matter and Thermodynamics > Applications of Expansion of Solids Linear expansion or longitudinal expansion refers to the increase in length of a solid material when its temperature rises. This phenomenon occurs due to the increased thermal energy within the material, causing its constituent particles to vibrate more vigorously, […]

Expansion of Solids
Science > Physics > Thermal Properties of Matter and Thermodynamics > Expansion of Solids Whenever there is an increase in the dimensions of a body due to heating, then the body is said to be expanded and the phenomenon is known as expansion of solids. Solids undergo three types of expansions a) Linear (Longitudinal) expansions, […]
