Anichrome wire and an aluminum wire, each with the same initial resistance, have the same change in resistance when heated separately. (ρal = 2.82 × 10^−8 ω ⋅ m; αal = 3.9 × 10^−3/°c; ρnichrome = 1.50 × 10^−6 ω ⋅ m; αnichrome = 0.40 × 10^−3/°c.) the ratio of the temperature change of the nichrome wire to the temperature change of the aluminum wire
