Thermal expansion is the tendency of change in shape of the material with respect to change in temperature.
If the change in material is linear then that change is known as linear expansion of material.
The length of the material increases with increase in temperature. That is, the expression for the new length of the material is as follows:

Here,  is initial length,  is the coefficient of thermal expansion of the material, and  is the change in temperature.
