Question

Electric conductivities of solid $\left(X\right)$ is ${10}^4-{10}^{7}oh{m}^{-1}{m}^{-1}$ and solid $\left(Y\right)$ is ${10}^{-20}-{10}^{-10}oh{m}^{-1}{m}^{-1}$. Identify solid $\left(X\right)$ and solid $\left(Y\right)$ and write their name.

Answer 1

Electric conductivity of solid $\left(X\right)$ is ${10}^4-{10}^{7}oh{m}^{-1}{m}^{-1}$. It is a semiconductor such as silicon or germanium. Electric conductivity of solid $\left(Y\right)$ is ${10}^{-20}-{10}^{-10}oh{m}^{-1}{m}^{-1}$. It is an insulator such as diamond.
