Answer» Superficial Expansion of Solids: Expansion in AREA of a Laminar surface due to heating is known as superficial expansion. The COEFFICIENT of superficial expansion is defined as the ratio of increase in area to its original area for every degree increase in temperature.Coefficient of superficial expansion= Increase in area / (Initial area – Rise in TEMP) (° C)= 2 × coefficient of linear expansion Cubical Expansion of Solids: In the case of solids which have a definite shape, when they are HEATED they expand in all directions i.e., Length, Height and Width.Coefficient of cubical expansion= Increase in volume/(initial volume × rise in temp (°C)
