The values of conductivity of some materials at

298.15 \mathrm{~K}^{-1} ~\text{in} ~\mathrm{Sm}^{-1}

are

2.1 \times 10^3

,

1.0 \times 10^{-16}, 1.2 \times 10,3.91,1.5 \times 10^{-2}, 1 \times 10^{-7}, 1.0 \times 10^3

.

The number of conductors among the materials is _____________.

Accepted Answer

Conductivity (S m $^{- 1}$ )

$\begin{array}{l} 2.1 \times 10^{3} \\ 1.2 \times 10 \\ 3.91 \\ 1 \times 10^{3} \end{array}} conductors at 298.15 K$

$1 \times 10^{- 16} Insulator at 298.15 K$

$\begin{array}{l} 1.5 \times 10^{- 2} \\ 1 \times 10^{- 7} \end{array}} Semiconductor at 298.15 K$

Therefore number of conductors is 4.
