adsorption means that the molecules of one phase are present in higher concentration at the surface of the second phase.
ex.inert gases on charcoal
when the temperature is increasing the adsorption decreases.so , we can say the adsorption is always exothermic.
DG = DH - T DS
adsorption leads to decrease in entropy DS is negative because the adsorbate molecules gets lesser opportunity to move about on the surface of adsorbent also since adsorption is Spontaneous Process DH > TDS. So DG is negative
yes it does...even though physical adsorption is an exothermic reaction, its enthalpy of adsorption is pretty low aroun 20 to 40 kJ/mol
Is adsorption a chemical process in which one substance is taken up by another?
Exothermic is the process that exert heat or giving out energy to surrounding. Example of exothermic process such as condensing of steam or burning of fuel.
Anion are associated with exothermic process.

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

Exothermic/endothermic is a process not a feeling.
Exothermic
Crystallization is considered an exothermic process. Hand warmers use the process of sodium acetate crystallization to produce heat.
Anion are associated with exothermic process.
Exothermic
Adsorption on kaolinite is physical
Breaking bonds produces energy making it an exothermic process.
