Do raisins swell in rain water or mustard oil or saline water or saturated sugar solution?

Answers

Answered by Ramanarrora

Raisins contain hypertonic solution which gains water by endosmosis across the semi-permeable cell membrane of raisins. So,they swell up in tap water. When they are put in rainwater,they lose water by exosmosis and as a result they shrink.
