Determine at what temperature aluminum will have the same resistivity as tungsten does at 24 ∘
c.

The resistivity of tungsten can be determined using the empirical equation
Rw = 48.0 (1 + 4.8297 × 10^−3 T + 1.663 × 10^−6 (T^2))
Input the temperature to get the resistivity

For aluminum, you can look for the empirical equation for its resistivity but what is available is a graph between resistivity and temperature. Simply use the graph to determine which temperature will result to the same resistivity of tungsten at 24 C.
