Question

List the factors on which linear expansion depends upon.

Answer 1

1. When any matter is heated and there is an increase in its length, the expansion is called linear expansion.
2. There are two factors on which the linear expansion depends.
   1. Increase in temperature will lead to more linear expansion.
   2. The nature of the material also affects the amount of linear expansion.
3. Different materials experience different linear expansion.
4. Aluminium experiences double expansion than steel for the same change in temperature.
