# Linear Thermal Expansion of a Meter Stick

#### Ibraheem

Hello,

If a thermal linear expansion happens to a meter stick, for instance a 50 m steel meter stick, the new length would be 50(1+(coefficient of expansion )(ΔT)). My question is would this also work if we choose different segment of the meter stick?For example, Can the new length for the part from 0 to 10m of the meter stick be shown by 10(1+(coefficient of expansion )(ΔT))?

Yes, thermal expansion is a fraction of initial length, regardless of what segment you are looking at.

He has a 50 meters long "meter stick".
