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

A

1.3 x 10-3/K.

B

1.7 x 10-5/K

C

5.7 x 10-5/K

D

2.8 x 10-4/K
