1. A flat aluminum plate has a circular hole of diameter 1.858 cm at 0.00 °C.What is the change in its diameter when the temperature of the plate is increased to 114 °C? For reference, the coefficient of thermal expansion for aluminum is 2.3 x 10-5/C°. Give at least 2 significant figures in your answer, which should be in cm.
2.A flat plate made of an unknown metal has a circular hole of diameter 3 cm at 0.00 °C that increases in diameter by 0.005 when the temperature is raised from 0.00 °C to 111 °C. What is the coefficient of thermal expansion for this unknown metal. Express your answer in parts per million per degree Celsius (for example, an expansion coefficient of 23 x 10-6/°C would be 23 ppm/°C). However, enter only the numerical part of the answer.
