Answer:

When a metallic conductor is heated, the atoms in the metal vibrate with greater amplitude and frequency. Due to increase in temperature, the thermal velocities of free electrons also increases. ... This increases the opposition to the movement of electrons and hence the resistance of the conductor

Answer:

When metallic conductor is heated, the atoms in the metal is vibrate with greater amplitude and frequency.

Due to increase in temperature, the thermal velocity of free electron also increases.....

This increases the opposition the movement of electron and hence the resistance of conductor.
