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

Is dissolving salt in water reversible or irreversible?

This is a reversible process.


Are reversible changes and physical changes the same?

Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.


Are all physical changes are reversible changes?

Not all physical changes are reversible. Some physical changes, such as breaking a glass or cutting a piece of paper, are irreversible because they result in a permanent change to the material's structure. Reversible changes, like melting ice or boiling water, are changes that can be easily reversed by altering the conditions.


Is boiling water to make tea a chemical reaction or a reversible change?

Boiling water to make tea is a reversible physical change. When water boils, it changes from liquid to gas, but it can easily be reversed by cooling the gas back into liquid form. No new substances are formed during this process, indicating that it is a physical change, not a chemical reaction.


What is an example of a physical change that is not reversible?

Melting ice cubes to form water is an example of a physical change that is not reversible. Once the ice cubes have melted into water, it is not possible to reverse the process and turn the water back into ice cubes without additional processes like freezing.

Does physical adsorption have a low adsorption enthalpy?

Yes, physical adsorption typically has a low adsorption enthalpy due to weak van der Waals forces between the adsorbate and adsorbent. These interactions are reversible and non-specific, leading to lower enthalpies compared to chemical adsorption.


Is kaolin a physical or a chemical process?

Adsorption on kaolinite is physical


Is adsorption a chemical process in which one substance is taken up by another?

Yes, adsorption is a process in which one substance (the adsorbate) is attracted and binds to the surface of another material (the adsorbent) through physical or chemical interactions. This results in a concentration of the adsorbate at the surface of the adsorbent.


What is the definition of physisorption?

Physisorption is the reversible adsorption of molecules onto a surface due to weak van der Waals forces. It involves physical interactions rather than chemical bonds, and can occur in processes such as gas adsorption on solid surfaces.


Is water evaporating into steam a chemical or physical change?

It is a physical change because the change is reversible.


What are some examples of changes?

A mixture of salt and sand is an example of a physical change since the process is reversible.


Is dissolving salt in water reversible or irreversible?

This is a reversible process.


Is crystallization a reversible process?

Yes, crystallization is a reversible process. By carefully controlling factors such as temperature and concentration, you can both create crystals through crystallization and dissolve them back into a solution. This reversibility is a key aspect of the crystallization process, which makes it useful in various applications.

What chemical reactions are reversible?

All physical changes are reversible.
