The temperature dependence of resistances of Cu and undoped Si

The temperature dependence of resistances of Cu and undoped Si in the temperature range 300-400 K, is best described by :

  1. Linear  increase for Cu,  linear increase for Si
  2. Linear  increase for Cu, exponential increase for Si.
  3. Linear increase for Cu, exponential decrease for Si.
  4. Linear decrease  for  Cu, linear decrease for Si.
