The resistivity of Cu at 0C is 1.30 x 10-8 2.m. The change in resistivity per degree Celsius is 0.02 x 10-8 2.m. A Cu wire of length 10 cm is heated from 0C to a new temperature T. The resistivity at this temperature is 15.3 x 10-8 2.m and the length of the wire is 10.4 cm. Calculate the thermal expansion coefficient of Cu.
