Assertion : The resistivity of a semiconductor increases with temperature. Reason: In a conducting solid, the rate of collisions between free electrons and ions increases with increase of temperature.

Statement 1: Conductivity of semiconductors decreases with increase in temperature Statement-2: More electron goes from valance band to conduction band with increase in temperature.

Statement 1: Conductivity of semiconductor increases with increase in temperature. Statement 2: Forbidden energy gap is highest for semiconductors.

Assertion: Resistivity of a metal conductor increases with the increase in temperature. Reason: When the temperature of a conductor is increased then the number of free electrons per unit volumic increases.

Which of the following is correct for the decrease in the physical adsorption with increase of temperature

Statement-1: Conductivity of a metallic conductor decreases with increases in temperature. Statement-2: On increasing temperature, collision of electrons becomes more frequent and number of free electrons in the metallic conductor decreases.
