Question

What do we mean by the statement;the linear expansivity of a metal is 0.0004415 per kelvin.​

Answer 1

Step-by-step explanation:

Given

coefficient of linear expansion of metal is
`0.0004415` 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
`^(\circ)C^(-1)\ \text{or}\ K^(-1)`

The given value indicates there will be
`0.0004415` unit change in length on
`1\ K` temperature change.
