###### A length of aluminum wire has a resistance of \$30.0 Omega\$ at \$20.0^{circ} mathrm{C}\$. When the wire is warmed in an oven and reaches thermal equilibrium, the resistance of the wire increases to \$46.2 Omega\$ (a) Neglecting thermal expansion, find the temperature of the oven. (b) Qualitatively, how would thermal expansion be expected to affect the answer?
