The coefficient of linear expansion of a mystery metal alloy is 1.20 x 10-5 K 1. At 20.0° C a rod made of this alloy has a length of 11.9200 m. The rod is cooled to -29.0° C. Calculate the change in length (AL) of the rod. Remember that a negative change in length means that the length decreases, and a positive change in length means that the length increases. (There must be three significant figures in your answer.) x...
