Question
Suppose that at room temperature, a certain aluminum bar is 1.0000 m long. The bar gets
longer when its temperature is raised. The length l of the bar obeys the following relation:
1.0000 + 2.4 x 10-³T, where T is the number of degrees Celsius above room
temperature. What is the change of the bar's length if the temperature is raised to 18.3 °C
above room temperature?
Express your answer in meters to two significant figures.
