Temperature co-efficent of resistance for metals is

the temperature co-efficient of resistance for alloys is

The resistance of a wire at 300 K is found to be 0.3Omega . If the temperature co-efficent of resistance of wire is 1.5xx10^(-3)K^(-1) , the temperature at which the resistance becomes 0.6Omega is

The temperature coefficient of resistance increases for the metals when ________
