Hi friends plz answer for all these questions if you know answer it otherwise not answer it

Answer:
A . the process by which a solid holds molecules of a GAS or liquid or solute as a thin film is called adsorption while the process of a liquid , gas or other substances being taken in is called absorption
b. An adsorbent is a solid substance used to collect solute molecules from a liquid or gas . Adsorption is often used to extract pollutants by causing them to be attached to absorbents such as activated carbon or silica gel. Absorbents are porous solids which bind liquid or gaseous Molecule to their surface , while introduction to adsorbate diffusion , potential energy landscape . adsorbate diffusion is the process by mean of which adsorbates bonded to a solid surface can change their adsorption position due to influence of thermal fluctuations.
C. depending upon the nature of the force involved , two main types of adsorption process may be distinguished. physical adsorption or the physisorption²) . chemical adsorption or chemisorption . the third type of adsorption ,which is referred to, as activated adsorption is also known. boiling point of adsorbate
D . adsorption is defined as the deposition of the molecular species onto the surface . the molecular species that get absorbed on the surface is known adsorbate and the surfaces on which adsorption occurs is known as adsorbent. common example clay, silica gel, collloid, metal, etc
