Answer:
The more these atoms and molecules bounce around, the harder it is for the electrons to get by. Thus, resistance generally increases with temperature. For small temperature changes the resistivity varies linearly with temperature: r = ro (1 + a DT), where a is the temperature coefficient of resistivity.
