    The variation of resistance and resistivity with temperature On considering some materials such as silver ,aluminium, copper consists of number of free electron s flowing through itthis type of materials conduct current easily that means that they are very less reactiveBut the resistivity of the material highly depend upon the temperature .Thus this explains that the metals offer more electrical resistance if temperature is increasedOn the other hand in non metals if the temperature is increased the resistance is decreases Temperature  The temperature is a physical property that expresses the degree or intensity of a heat in a substance or matter.
