An aluminum rod is measured with a steel tape at 25°C. The reading is exactly 1.000 m long. Determine the steel tape measure's “reading" of the aluminum rod in the following cases. Will the “reading" be (1) more than, (2) the same as, or (3) less than 1.000 m? [Hint: A simple sketch for each case might be helpful. Both the aluminum rod and steel tape will expand or shrink as temperature changes.] [The coefficients of linear expansion for steel and aluminum are on the first page of this lab.] 1. (a) only the steel tape is cooled to 0°C, (b) only the aluminum rod is cooled to 0°C, (c) both the steel tape and aluminum rod are cooled to 0°C,
