How does the resistance of: i) a semiconductor ii) an alloyvary with temperature?

i) The resistance decreases with increase in the temperature. The resistance is directly proportional to the temperature.
ii) The resistance of an alloy remains nearly unaffected by the change in temperature. In alloys, like constantan, atoms are in disorder so alloys have big resistivity. Their additional disorder due to temperature increase is insignificant.
