Use the data in Table 2 to answer the following:
Which is a better conductor, iron or mercury?

Explanation

The electrical resistivity of iron is `10.0 xx 10^(-8) Omegam` whereas that of mercury is `94.0 xx 10^(-8)Omegam`. As the resistivity of iron is less than that of mercury, iron (Fe) is a better conductor than mercury (Hg).
