How does the resistance of the following change with rhe rise in temperature? pure metals and German silver and carbon

In pure metals, resistance increases with rise in temperature.

In alloys such as Gold, Silver and Germanium, the rise in temperature results in increased resistance but the resistance in alloys is relatively lower than in pure metals.

Explanation:

Resistivity increases with increasing temperature in conductors and decreases with increasing temperature in insulators.

resistance in the increasing order from least to maximum:

German silver, pure metals, carbon
