Answer 2

Answer:

Explanation:

A) Linear expansion : The increase in the length of a solid on heating is called linear expansion. It depends on 3 factors (i)Original length of the rod (ii) Increase in temperature (iii) Material of the rod

B) Superficial Expansion: The increase in the area of a solid on heating is called superficial expansion. It depends on 3 factors (i)initial area of plate

(ii) increase in temperature (iii) Material of plate

C) Cubical expansion: The increase in the volume of a solid on heating is called cubical expansion. It also depends on 3 factors (i) Initial volume  of solid (ii) rise in temperature (iii) Material of solid
