Molecular formula : MW : CAS :
nature : insoluble gas dispersed in a liquid or solid melting formed by the dispersion system. Volume of linear 10-5 cm in size over. Its shape often varies environment. For example, soap bubbles, beer foam gases are dispersed in the liquid dispersion system. Again foam, foam rubber, foam glass gases are dispersed in the molten solid dispersion system, the cooling derived.
