What is thermal expansion? What are its types?
Asked by Topperlearning User | 13th Apr, 2015, 03:28: PM
All solids expand on heating. This phenomenon is called thermal expansion.
The types of thermal expansion are:
a. Linear Expansion
In linear expansion there is an increase in length of the solid on heating.
α is known as the coefficient of linear expansion.
b. Aerial or Superficial Expansion
In superficial expansion there is an increase in the surface area of the solid on heating.
β is known as the coefficient of areal/superficial expansion.
c. Cubical Expansion
There is increase in volume of solid on heating.
γ is known as the coefficient of cubical expansion.
