Why does the speed of sound increase with increase in temperature?

Why does physisorption decrease with increase of temperature ?

The solubility of NaCl in water decreases with increases in temperature.

Why does physisorption decrease with the increase of temperature ?

Assertion (A): pH of water increases with an increase in temperature. Reason (R) : K_(w) or water increases with increase in temperature.

Adsorption is accompanied by the evolution of heat. Thus, according to Le Chatelier's principle the amount of surface adsorbed should (i) decrease with increase in temperature (ii) decrease with decrease in temperature (iii) increase with increase in temperature (iv) increase with decrease in temperature
