Statement - I : The drift velocity of electrons in a metallic wire will decrease, if the temperature of the wire is increased. 
Statement – II: On increasing temperature, conductivity of metallic wire decreases.

On the increasing temperature of the wire the K.E. of electrons increases and so they collide more rapidly with each other and hence their drift velocities decreases. 

Resistivity also increases and resistivity is inversely proportional to the conductivity of a material.
