Use the following information to answer the next question. The length of a copper rod at 35°C is measured to be 1.5 m by an aluminium tape, which is correct at 15°C. Assume that the coefficients of linear expansion for aluminium and copper are 2.5 × 10 − 15/K and 1.7 × 10 − 5/K respectively. What is the length of the copper rod at temperature 15°C? |
