Assertion : When temperature of a conductor is increased, its resistance increases.
Reason : Free electrons collide more frequently.

When the temperature of a metallic conductor is increased, its resistance

On increasing the temperature of a conductor, its resistance increases because

On increasing the temperature of a conductor, its resistance increases because

On increasing the temperature of a conductor, its resistance increases because

Assertion (A): The rate of reaction increases with increase in temperature. Reason (R): The reactant molecules collide less frequency.

A: When temperature of a metallic wire is increased, its resistance increase . R : As the temperature is increaed , average relaxtion time increase.
