Setler79 [48]

Answer:

0.07 m

Explanation:

L_0 = Initial length = 1 km = 1000 m

\Delta T = Change in temperature =  1.00°C

\alpha = Coefficient of linear thermal expansion

Volumetric coefficient of expansion of water

\beta=210\times 10^{-6}^{\circ}C\\\Rightarrow \beta=3\alpha\\\Rightarrow \alpha=\dfrac{\beta}{3}\\\Rightarrow \alpha=\dfrac{210\times 10^{-6}}{3}\\\Rightarrow \alpha=70\times 10^{-6}\ ^{\circ}C

Change in length is given by

\Delta L=L_0\alpha \Delta T\\\Rightarrow \Delta L=1000\times 1\times 70\times 10^{-6}\\\Rightarrow \Delta L=0.07\ m

The change in length is 0.07 m
