In terms of particles, explain how resistance arises in metal conductors and why does this resistance increases with temperature.

Resistance is due to the collision of free electrons with the metal ions of the conductor. When the temperture increases, the metal ions have more energy and vibrate. This increases the frequency of collisions between free electrons and the metal ions, and therefore increasing the resistance.
