(a) Using the data in Figure 12.8, determine the values of ρ0 and a from Equation 12.10 for pure copper. Take the temperature T to be in degrees Celsius.

(b) Determine the value of A in Equation 12.11 for nickel as an impurity in copper, using the data in Figure 12.8.

(c) Using the results of parts (a) and (b), estimate the electrical resistivity of copper containing 1.75 at% Ni at 100 C

Figure 12.8 The electrical resistivity versus temperature for copper and three copper–nickel alloys, one of which has been deformed.Thermal, impurity, and deformation contributions to the resistivity are indicated at –100°C.
