To understand this better, we need to look at how water and detergents interact. Hot water has more kinetic energy than cold water, meaning the molecules in the water move around more quickly. When these molecules interact with the surfactants in classic detergents, the greater energy they posse...
molecules, the extract decomposition rate increase is slower than that of the extraction rate. However, the decomposition persists on the available extracted substances. Therefore, long residence time resulted in higher extent of decomposition, leading to a decrease in total dissolved solids in ...
Research claims that this is down to chemical kinetics. Tea leaves contain flavour compounds that are heat sensitive. When hot water is poured over the leaves, energy from the heat makes water molecules move a lot faster allowing flavour extraction to be quick. When cold water is applied, the...
(those involving the ground state) of the most common atoms, ions, and molecules occur in the UV spectral range below 300nm; (2) veryhot stars, having surface temperatures in excess of 10,000K (vs ∼5800K for our sun), emit much or most of their radiation in the ground-inaccessible...
In fact, hot prpcessed soaps do need to cure as long, or longer than cold process. Soap is a salt of a fatty acid…..with a crystalline structure. The crystals move around during cure as the soap loses water molecules. The pH lowers slightly during this long process which makes a ...

A hypothesis is that due to the limited disruption of the crystalline structure, a small number of phenolic molecules can complex with starch matrix in the amorphous region. As starch granules are completely gelatinized with a full disruption of crystalline structure, more phenolics will penetrate ...
In this gas, the atoms and molecules of the elements fly around freely, bumping into each other and everything else. As these particles collide against an object, each of them pushes with a tiny amount of energy. Because there are so many particles in the air, this energy adds up to a...
molecules into the bloodstream. When this response is repeated over months, these moleculesassistin the formation of new blood vessels and repair damaged ones. This can help lower blood pressure as well as increase oxygen and glucose delivery to the muscle, which collectively can reduce ...
by changing the excitation wavelength); (3) high density of hot electrons in a spatially well-defined volume near a plasmonic metal surface, from where they can be efficiently extracted before they thermalise in the metal by engineering resonant charge transfer to proximal molecules or ...
