The values of conductivity of some materials at298.15 K in Sm-1 are 2....
Explanation:
Conductors:
- Materials with high conductivity values (2.1x10^3, 1.2x10^3) are considered conductors.
- Conductors allow the flow of electric current due to the presence of a large number of free electrons.
Insulators:
- Materials with very low conductivity values (1.0x10^-16, 1.0x10^-7) are considered insulators.
- Insulators do not allow the flow of electric current as they have very few free electrons.
Semiconductors:
- Materials with moderate conductivity values (3.91, 1.5x10^-2) are considered semiconductors.
- Semiconductors have conductivity values between conductors and insulators.
Conclusion:
- Out of the given materials, four have high conductivity values, indicating that they are conductors. The rest are either insulators or semiconductors.
