As we know Cu is conductor, so with increase in temperature, resistance will increase. Then, Si is semiconductor, so with increase in temperature, resistance will decreases.

Q. The temperature dependence of resistances of $C u$ and undoped $S i$ in the temperature range $300 - 400 K$ , is best described by :

Linear increase for Cu, linear increase for Si.

Linear increase for Cu, exponential increase for Si.

Linear increase for Cu, exponential decrease for Si.

Linear decrease for Cu, linear decrease for Si.

As we know $C u$ is conductor, so with increase in temperature, resistance will increase. Then, $S i$ is semiconductor, so with increase in temperature, resistance will decreases.
