Answer:
Explanation:
Given
coefficient of linear expansion of metal is [tex]0.0004415[/tex] per kelvin
When expansion or contraction occurs in linear direction then it called linear expansion . It indicates rate of change of length of metal with respect to temperature in kelvin. The S.I. unit is [tex]^{\circ}C^{-1}\ \text{or}\ K^{-1}[/tex]
The given value indicates there will be [tex]0.0004415[/tex] unit change in length on [tex]1\ K[/tex] temperature change.
