Here the adsorbate is held by adsorbant by weak Van Der Waal Forces which break when Temp incrses....
Thus, Physisorption decreases with Temp...Simple
Samudrajeet Baruah answered this
Physisorption is exothermic in nature. Therefore, in accordance to Le-Chateliere's Principal, Physisorption decreases with increase in temperature. This means it occurs more readily at low temperature
Ashwini answered this
Why are powedered substances more effective adsorbents than their crystalline form
Kajal😎👩✈️ Rathore answered this
Because in this adsorbate and adsorbent bound through weak vander waal force (universal force) and on increasing temperature bond disassociate
Miya answered this
Since the adsorption process is exothermic raise in temperature decrease the extend of adsorption. [According to le chatliers principle increase of temperature direct the reaction towards endothermic]

In physisorption the attractive forces between adsorbent and its molecules are weak Vander wall's forces. when temperature is increased kinetic energy of molecules of gas increases and they can easily the surface of absorbent because of weak forces.
