Question

3. Define conductivity. How can materials be classified based on their conductivity?​

Answer 1

Answer:

a measure of ability of a given substance to conduct electric current or heat

Explanation:

materials can be classified on the basis of conductivity as it resist flow of electric current or not

Answer 2

• The ability of an electrolyte solution to conduct electricity is defined by its conductivity (or specific conductance).

• Many industrial and environmental applications rely on conductivity tests to determine the ionic concentration of a solution because they are quick, cheap, and accurate.

• The measuring of product conductivity, for example, is a common approach to track and monitor the operation of water purification systems over time.

• Temperature effects on the electrolytic conductivity of ultra-pure water.
• Conductivity is frequently associated to the total dissolved solids (TDS) (TDS).
• At 25 degrees Celsius, high-quality deionized water has a conductivity of around 0.05 S/cm, average drinking water has a conductivity of 200–800 S/cm, and sea water has a conductivity of about 50 mS/cm (or 50,000 S/cm).
