Physisorption is exothermic in nature. Therefore, in accordance with Le-Chatliers principle, it decreases with increase in temperature. This means physisorption occurs at low temperature more readily. So, The correct order of temperature for curves I, II, III, IV are :

$T_{4} > T_{3} > T_{2} > T_{1}$
