Question

example of linear expansion with explanation.​

Answer 1

Answer:

For example, a steel bridge 100 m long will expand 10 times as much as a steel rail 10 meters long when both are heated equally. ... The original length (Lo of the bridge is 100 m, the coefficient of linear expansion of steel is 0.000012 per °C, and the rise in temperature (t) is 27 - 2 = 25°C.
