Question

Define coefficient of cubical expansion of solid. obtain expresion for it

Answer 1

Coefficient of volumetric expansion ( ) is defined as: "increase in volume per unit original volume per Kelvin rise in temperature is called coefficient of volumetric expansion.".

Answer 2

The increase in volume of solid due to heating it by 1 kelvin at constant pressure is known as coffecient of cubical expansion. In simple terms it is constant which is 3 times of coefficient of linear expansion
