1.	What is the process called when the molecules of a substance are retained at the surface of a solid or a liquid?(a) Absorption(b) Adsorption(c) Sorption(d) DesorptionThe question was posed to me during an interview.I'd like to ask this question from Surface Chemistry topic in section Surface Chemistry of Chemistry – Class 12
Answer» Right option is (B) Adsorption Easiest explanation: Adsorption is the PROCESS which involves the ACCUMULATION of the molecules of a substance in higher concentration on the SURFACE of a solid or a liquid. For example, GASSES are adsorbed on the surface of charcoal.
