The resistance of pure metals generally increases with a rise in temperature. Here's why:

1. At a higher temperature, the atoms of the metal vibrate more rapidly because of the increased energy.

2. This increased vibration leads to more frequent collisions between the electrons and the atoms as the electrons move through the metal.

3. These collisions impede the flow of electrons and hence increase the resistance of the metal.

4. Therefore, the resistance of a metal increases as the temperature increases.

This is a simplified explanation and the actual process involves quantum mechanics.
