#### Answer:

#### Explanation:

The coefficient of linear expansion is the fractional increase in length for a rise in temperature of 1 degree (deg C or Kelvin).

This means that if the length was doubled with a rise of 1 degree then the coefficient would be 2.

For most materials the numbers are much smaller.
