Question

Is conductivity a physical or chemical property?

Answer 1

Hint: Boiling point, melting point, size, shape etc are the physical properties. By reaction with others if there is any change occurred in the chemical composition of the chemical then it is called chemical property.

Complete answer:
- In the question it is asked is conductivity a physical or chemical property.
- The property of a chemical to allow the electrons or heat to pass through it is called conductivity.
- If the substance is not allowing the electrons or heat to pass through it is called an insulator.
- The substance which allows the passage of the electrons or heat by increasing the temperature then the substance is called semiconductor.
- Now we have to find conductivity is a physical property or chemical property.
- By passing the conductivity through a chemical the composition of the chemical is not going to change.
- Means copper is a good conductor, by passing electricity through the copper wire, the chemical composition is not going to change.
- Therefore conductivity is not a chemical property, it is a physical property.
- As the resistance decreases the conductivity is going to increase and vice versa.
- So, conductivity is a chemical property.

Note:
The salt solution is an example for conductors. Pure water is a bad conductor. By adding the salt to the pure water, the formed salt solution is going to act as a conductor by making the moment of the sodium cation and chloride anion in the solution.
