Answer:
1)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.
2)Area or superficial Expansion: Superficial expansion is defined as the increase in surface area of the solid on heating. If you consider at 00C area of a solid is A0 then its area at t0c is given by: A0(l+βt). Unit of β is 0C-1 or K-1. Where β is known as the coefficient of superficial expansion
3)The expansion of alcohol in a thermometer is one of many commonly encountered examples of thermal expansion, the change in size or volume of a given mass with temperature. ... Railroad tracks and bridges, for example, have expansion joints to allow them to freely expand and contract with temperature changes
