What is temperature coefficient of resistance of the material of conductor ?

Define temperature coefficient of resistance of the material of a conductor.

How does the resistivity of a conductor vary with temperature?

Calcualte the temperature at which the resistance of a conductor becomes 20% more than its resistance at 27^@C . The value of the temperature coefficient of resistance of the conductor is 2.0 xx 10^-4 K^-1
