Definitions and Concepts for AQA Chemistry A-level Physical Chemistry I 1.1: Atomic Structure Acceleration: Second stage of TOF spectrometry. The positively charged ions a re accelerated by an electric field so that they have the same kinetic energy. Atom: The smallest part of an element that can exist. All substances are made up of atoms.

Solution: A homogeneous mixture (usually with one component in larger amount); normally. a liquid [e.g. seawater; hydrochloric acid ], but the term may be also apply to a solid, but not to a gas. Solvent: The component of a solution in largest amount [e.g. the water of seawater].
Jul 3, 2019 · Definition: Absorption is the process by which atoms, molecules, or ions enter a bulk phase (liquid, gas, solid). Absorption differs from from adsorption, since the atoms/molecules/ions are taken up by the volume, not by surface. Examples: absorption of carbon dioxide by sodium hydroxide.

ALPHABETIZATION. The terms in the McGraw-Hill Dictionary of Chemistry, Second Edition, are alphabetized on a letter-by-letter basis; word spacing, hyphen, comma, solidus, and apostrophe in a term are ignored in the sequenc-ing. Also ignored in the sequencing of terms (usually chemical compounds) are italic elements, numbers, small capitals, and Gre...
FORMAT. The basic format for a defining entry provides the term in boldface, the field is small capitals, and the single definition in lightface: term [FIELD] Definition A term may be followed by multiple definitions, each introduced by a bold-face number: term [FIELD] 1. Definition. 2. Definition. 3. Definition. A term may have definitions in two ...

What is the difference between adsorption and absorption?
What is absorption in spectrophotometry?
What is an example of absorption?
Is absorption an endothermic process?
Why is adsorption an exothermic process?
Jul 15, 2021 · Adsorption and absorption are two sorption processes through which one substance attaches to another. The main difference between them is that adsorption is the adhesion of particles onto a substance, while absorption involves mass transfer into another material. But, adsorption and absorption involve other differences as well.
