Chapter 28, Problem 1PQ

To determine

The better conductor metal.

Answer to Problem 1PQ

The better conductor metal is metal 1.

Explanation of Solution

The identical metal conductor, metal 1 and metal 2 are having same number of conduction electrons per unit volume. But the collision of the conduction electrons per unit time is less in metal 1 compared to the metal 2.

When the collision of conduction electron increases in a metal conductor, the electrical resistance of the metal conductor also increases. This will reduce the electric conduction in the metal.

Conclusion:

Thus, the metal 1 which has less collision of conduction electrons per unit time will be the better conductor.
