Solved Example Problems for Thermal expansion of solids, liquids and gases

EXAMPLE 8.6

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 α = 10 ×10−6 per °C

Solution

ΔL = 10 × 10−6 Ã— 300 × 23 = 0.69 m=69 cm
