The coefficient of thermal expansion of aluminum is 22.9 . Using a device similar to that described in the experiment (see pages 3 and 4), an aluminum rod 50.1 cm long is inserted. The initial temperature of the rod is 22 °C. If the final temperature of the rod is 99 °C, what is the new length of the rod in centimeters? Calculate your answer to five significant digits
Answer - 50.188cm
1. The coefficient of thermal expansion is [c] cross times 10 to the power of negative 6 end exponent degree C. Using a device similar to that described in the experiment (see pages 3 and 4), an aluminum rod 50.1 cm long is inserted. The initial temperature of the rod is 22 °C. Using a device similar to that described in the experiment, an aluminum rod 40.1 cm long is inserted. The initial temperature of the rod is 22 °C. The initial reading of the main scale is 3 and the reading of the auxiliary scale is 27. If the rod is now heated to a temperature of 99 °C, what is the new main scale reading?
