Answer:
The change in length is 0.01056 m.
Explanation:
Given that,
Length = 11 m
Temperature = 20°C
Pressure = 1 atm
Boiling temperature = 100°C
We need to calculate the length
Using formula of change in linear expansion
[tex]\dfrac{\Delta L}{L}=\alpha_{l}\Delta T[/tex]
[tex]\Delta L=L\times\alpha_{l}\times(T_{f}-T_{i})[/tex]
Put the value into the formula
[tex]\Delta L=11\times12\times10^{-6}\times(100-20)[/tex]
[tex]\Delta L=11\times12\times10^{-6}\times80[/tex]
[tex]\Delta L=0.01056\ m[/tex]
Hence, The change in length is 0.01056 m.
