no

adsorption is processs of accumulation of liquid/gases on solid surface. reversible adsorption is seen in physical adsorption where increase in pressure increases the adsorption and decrease in pressure decrease adsorption of molecules to surface that is desorption takes place

yes it does...even though physical adsorption is an exothermic reaction, its enthalpy of adsorption is pretty low aroun 20 to 40 kJ/mol

Adsorption is a very similar word to absorption but they are not the same thing really. Adsorption can be used to rid methane smells and such where absorption is what a sponge does to water.
