ViviAdsorption is the process by which molecules of a substance adhere to the surface of another substance, while condensation is the phase transition from gas to liquid when molecules lose energy and come together to form a liquid. Adsorption involves surface attraction, whereas condensation involves a change in physical state.

What is difference between adsorption and biosorption?
Adsorption is the process by which a substance is attached to the surface of a solid material. Biosorption, on the other hand, involves the use of living or dead biomass to remove pollutants from a solution. Biosorption is a specific type of adsorption that relies on biological processes to remove contaminants.
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.
What is the kids definition of condensation?
Condensation is when water vapor in the air cools down and turns into liquid water droplets. You can see condensation on a cold drink or on a window on a cold day.
What is the difference between film and dropwise condensation?
Film condensation occurs when a continuous liquid film forms on a surface during the condensation process, while dropwise condensation occurs when discrete droplets form on the surface. Dropwise condensation is more efficient in heat transfer compared to film condensation due to reduced resistance to heat transfer at the liquid-vapor interface.
What is the difference between vaporization sublimation and condensation?
Vaporization is the process of a substance changing from a liquid to a gas, sublimation is the process of a substance changing directly from a solid to a gas, and condensation is the process of a gas changing to a liquid. Each process involves the transformation of matter between different states.
