उत्तर
| Linear expansion | Cubical expansion | Superficial expansion |
| When a body is heated or cooled, the length of the body changes due to a change in its temperature. | If there is an increase in the volume of a solid body due to heating, it is called cubical expansion. | If there is an increase in the area of a solid object due to heating, then the expansion is called superficial expansion. |
| The ratio of increase in the length of the body per degree rise in temperature to its unit length. | The ratio of increase in the volume of the body per degree rise in temperature to its unit volume is called a coefficient of cubical expansion. | The ratio of increase in the area of the body per degree rise in temperature to its unit area is called a coefficient of superficial expansion. |
