उत्तर
Extent of physisorption of a gas increases with decrease in temperature.
Explanation:
As the process of adsorption is an exothermic one; physical adsorption occurs readily at low temperature and decreases with an increase in the temperature as equilibrium shifts in the backward direction. This is known as Le-Chatelier's principle.
