A length of aluminum wire has a resistance of 14.0 ? at 22.0°C. When the wire is warmed in an oven and reaches thermal equilibrium, the resistance of the wire increases to 30.2 ?.
(a) Neglecting thermal expansion, find the temperature of the oven.
°C
(b) Qualitatively, how would thermal expansion be expected to affect the answer?
