Question

the expansion of a solid body depend on

Answer 1

Thermal expansion is the change in size of an object as its temperature changes. Normally, as the temperature increases, the size of an object also increases. Conversely, most objects shrink as the temperature drops. On a hot summer day, electrical power lines sag between power poles. The sag occurs because the wires grow longer as the temperature increases. Long bridges often have interlocking metal fingers along the joints where sections of the bridge are joined to each other. The metal fingers allow the bridge sections to expand and contract with changes in the temperature

Answer 2

the expansion of solid body depends upon the force applied and the elasticity of the body and mostly solid bodies show plasticity that is they don't how much elasticity that also some external factors that affect the expansion of a solid body such as temperature
