Name a substance whose resistance decreases with the increase in temperature.

Resistance increases with increases in temperature for

Why does physisorption decrease with the increase of temperature ?

Incandescent bulbs are designed by keeping in mind that the resistance of their filament increases with the increase in temperature. If at room temperature, 100W, 60W and 40W bulbs have filament resistances R_(100), R_(60) and R_(40) , respectively, the relation between these resistances is

STATEMENT-1 : As temperature of a conducting wire increases, the slope of V-I graph ( V on y - axis and I on x-axis ) increases. and STATEMENT-2 : For a conductor, the resistance increases with increase in temperature.

Why does physisorption decrease with increase of temperature ?

Name one material whose resistivity decreases with rise in temperature. Explain briefly on the basis of free electron theory why the resistivity decreases.

Statement-1 : In a Meter Bridge experiment, null point for an unknown resistance is measured. Now, the unknown resistance is put inside an enclosure maintained at a higher temperature. The null point can be obtained at the same point as before by decreasing the value of the standard resistance. Statement-2 : Resistance of metal increases with increase in temperature.
