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, […]
