Question

State true or false.
The resistivity of all pure metals increases with the rise in temperature.

• A. True
• B. False

Answer 1

The correct option is A

True

The resistivity of all pure metals increases with the rise in temperature. As the temperature of the material increases, the energy possessed by metal atoms also increases, as a result of which the the vibration of the entities increases. More vibration results in an increase of hinderance to the motion of electrons, thus offering more resistance to the passage of current.
