Question:

Which most likely has the greatest conductivity? a warm plastic rod a cool rubber tube a cool lead metal strip a warm copper wire

Answers

A warm copper wire. This is because of the material and the temperature: metal, in general, is a good conductor, and copper is better than lead. Also, electricity conducts better in warm environments than it does in cold environments - cooling wires will slow conductivity.

warm copper wire

Explanation:

Took the test on edge

The correct answer is a cool lead metal strip.

Explanation:

Conductivity is defined as the material's extent to allow an electric current to flow through it. It is inversely related to the temperature.

[tex]\text{Conductivity}\propto \frac{1}{\text{Temperature}}[/tex]

With increase in temperature, the conductivity decreases.

From the given options:

Option 1: A warm plastic rod

Plastic rod is an insulator and hence, we will not have conductivity.

Option 2: A cool rubber tube

Rubber tube is an insulator and hence, we will not have conductivity.

Option 3: A cool lead metal strip

Lead metal strip is a conductor and it will show conductivity and its conductivity will be high because the temperature is low.

Option 4: A warm copper wire

Copper wire is a conductor and it will show conductivity but its conductivity will be less because the temperature of the material is high.

Hence, the correct answer is Option 3.

A cool lead metal strip
The metallic nature of lead will make it a good conductor and the reduction of temperature will prevent interference to flow of electricity by reducing the random motion of electrons.
