Answer 2

Answer:

The coefficient of linear expansion is the change in length of a specimen one unit long when its temperature is changed by one degree ( see linear expansion ). A metal such as lead which has a low melting point and is relatively easily compressed, expands a great deal for a given rise in temperature.
