Science presenter Jon Chase demonstrates that a large piece of expanded polystyrene will dissolve in a very small volume of propanone. He defines the terms solute, solvent and solution. By dissolving ...

Solubility functions by a group of rules that determine how dissolvable a substance (solute) is in solvent and depends entirely on the physical and chemical properties of the solute and solvent. That ...

In the gaseous phase, vibrational-, rotational- and translational-energy transfer between small molecules can be observed experimentally from time-dependent optical spectra. Populations in the ...
