A length of aluminum wire has a resistance of 36.0 2 at 24.0°C. When the wire is warmed in an oven and reaches thermal equilibrium, the resistance of the wire increases to 51.5 Ω. (a) Neglecting thermal expansion, find the temperature of the oven. °C (b) Qualitatively, how would thermal expansion be expected to affect the answer?
