The three types of thermal expansions are

• Linear expansion

Expansion in length of solid bodies on heating is called linear expansion.

• Superficial expansion

superficial expansion is defined as when heat is given to any metallic object then the expansion takes place , when expansion takes place in area is termed as superficial expansion.

• Cubical expansion

Increase in volume of a body on heating is referred to as “VOLUMETRIC EXPANSION ” or “CUBICAL EXPANSION“.
