Answer» When raisins are kept in water for a few hours, the raisins will swell up or they will expand in size. This happens due to osmosis, which is the movement of molecules from a region of its higher to its lower concentration through a semi or selectively permeable membrane. Osmosis can be of two types, endosmosis ( the entering of solvent from high to low concentration) and exosmosis( the leaving of solvent from high to low concentration) So : When raisins are kept in water, the raisins has less solvent concentration and the water has comparatively more solvent concentration, which means that it will act as aHypotonic Solution. The raisins will act as a semi permeable membrane and water will move from the outer surroundings into the raisins (endosmosis) due to which the raisinwill increase in size or swell up. |
