Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle . [ 1 ] It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within ...
Alternative condensation conditions have been developed, including the use of Lewis acid catalysts. Preparation of resorcin[4]arenes from resorcinol and an aldehyde A green chemistry procedure uses solvent-free conditions: resorcinol, an aldehyde, and p -toluenesulfonic acid are ground together in a mortar and pestle at low temperature.
Generic hydrolysis reaction. (The 2-way yield symbol indicates a chemical equilibrium in which hydrolysis and condensation are reversible.). Hydrolysis (/ h aɪ ˈ d r ɒ l ɪ s ɪ s /; from Ancient Greek hydro- 'water' and lysis 'to unbind') is any chemical reaction in which a molecule of water breaks one or more chemical bonds.
Condensation reactions likely played major roles in the synthesis of the first biotic molecules including early peptides and nucleic acids.In fact, condensation reactions would be required at multiple steps in RNA oligomerization: the condensation of nucleobases and sugars, nucleoside phosphorylation, and nucleotide polymerization.
The first problem is a thermodynamic one: most aldol reactions are reversible. Furthermore, the equilibrium is also just barely on the side of the products in the case of simple aldehyde–ketone aldol reactions. [2] If the conditions are particularly harsh (e.g.: NaOMe/MeOH/reflux), condensation may occur.

When there is mechanical lift to saturation, cloud base begins at the lifted condensation level (LCL); absent forcing, cloud base begins at the convective condensation level (CCL) where heating from below causes spontaneous buoyant lifting to the point of condensation when the convective temperature is reached.
Technically, anything over 20 years old can be coined "vintage." But when you truly think of items worth this title, your brain doesn't go to Beanie Babies. Instead, it conjures up images of vinyl...
