Raisins are just dried grapes, so when raisins are kept in water they re-absorb liquid (that they lost in the drying process). They swell to accommodate the new liquid.
Yes, the raisins will swell due to osmosis, where the solvent goes from a low solute concentration to a higher solute concentration, which in this case, is from the distilled water to inside the raisin.
When raisins are soaked in water, they absorb the water and swell up, becoming plumper and softer. This process is called rehydration.
Because water passes out of the raisins [region of higher concentration] into the salt solution [region of lower concentration] through the semipermeable membrane.
it soaks up and turns softer .but does not turn back to a grape it soaks up and turns softer .but does not turn back to a grape
Because they absorb the water they're in - which makes them swell up.
It is an example of hypotonic solution and the raisins will swell up.
Pulses swell when kept in water because they absorb the water through a process called osmosis. Osmosis is the movement of water molecules from an area of high concentration (outside the pulse) to an area of low concentration (inside the pulse), causing it to swell as the water enters its structure.
If a raisin is kept in a salt solution, water will move out of the raisin due to osmosis. This will cause the raisin to shrink and dehydrate as water flows from an area of higher concentration (inside the raisin) to an area of lower concentration (the salt solution).
osmosis!
it will swell
Yes.
when raisins are placed in concentrated solution of sugarthen they will swell up
