A nichrome wire and an aluminum wire, each with the same initial resistance, have the same change in resistance when heated separately. (rAl = 2.82  10-8 W  m; aAl = 3.9  10-3 / C; rnichrome = 1.50  10-6 W  m; anichrome = 0.40  10-3 / C.) The ratio of the temperature change of the nichrome wire to the temperature change of the aluminum wire is
 a. 0.019.
  b. 0.10.
  c. 0.18.
