Eiffel tower is made up of iron and its height is roughly 300 m. During winter season (January) in France the temperature is 2^(@)C and in hot summer its average temperature 25^(@)C. Calculate the change in height of Eiffel tower between summer and winter. The linear thermal expansion coefficient for iron alpha = 10xx10^(-6)" per "^(@)C

Answer»

Solution :`(DeltaL)/(L) = alpha_L DeltaT = DeltaL = alpha_L L DeltaT`
`DeltaT = 10 xx 10^(-6) xx 300xx23 =0.69 m = 69 CM`
