Question

Answer

Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. ... Adsorption is a surface phenomenon, while absorption involves the whole volume of the material.

Answer

Adsorption the phenomenon of attracting and retaining the molecules of a substance on the surface of a solid or liquid resulting into higher concentration of the molecule on the surface is called adsorption, that's it.

Answer

Adsorption is a surface phenomenon while absorption is a bulk phenomenon....

Answer

It is a surface phenomenon where we see two types they are chemical adsorption and physical adsorption depending on the conditions survive kind of adsorption occurs

Answer

Adsorption is a surface phenomenon.

Adsorption is the process by which molecules or ions from a gas, liquid, or dissolved solid adhere to a surface. It is a surface phenomenon because it involves the accumulation of particles on the surface of a solid or liquid, rather than their dispersion throughout the bulk of the material. This can occur on solid surfaces (solid-gas or solid-liquid adsorption) or liquid surfaces (liquid-gas adsorption).

Explanation:

1. Definition of Adsorption:
Adsorption is defined as the process of the accumulation of molecules or ions on the surface of a solid or liquid. It is a surface phenomenon because it occurs at the interface between two phases.

2. Mechanism of Adsorption:
Adsorption occurs due to attractive forces between the adsorbate (the substance being adsorbed) and the adsorbent (the surface on which adsorption occurs). These attractive forces can be physical or chemical in nature.

3. Physical Adsorption:
Physical adsorption, also known as physisorption, is characterized by weak van der Waals forces between the adsorbate and adsorbent. It occurs at relatively low temperatures and can be reversed by increasing the temperature or decreasing the pressure. Physical adsorption is a surface phenomenon as it involves the accumulation of particles on the surface.

4. Chemical Adsorption:
Chemical adsorption, also known as chemisorption, involves the formation of chemical bonds between the adsorbate and adsorbent. It occurs at higher temperatures and is more specific in nature. Chemical adsorption is also a surface phenomenon as it occurs at the surface of the adsorbent.

5. Significance of Adsorption:
Adsorption plays a crucial role in various processes and industries. It is used in water purification, catalysis, gas separation, drug delivery systems, and many other applications. Understanding the surface phenomenon of adsorption is essential for optimizing these processes and designing efficient adsorbents.

In conclusion, adsorption is a surface phenomenon because it involves the accumulation of particles on the surface of a solid or liquid. It occurs due to attractive forces between the adsorbate and adsorbent, and it can be physical or chemical in nature. Adsorption has significant applications in various fields and understanding its surface nature is important for its practical utilization.

Answer

It is a surface phenomenon in which substance is attached to the surface of any other substance not inside the surface
for example: if we paint a ball, paint is attached only on the surface. so it is a surface phenomenon
