Because water passes out of the raisins [region of higher concentration] into the salt solution [region of lower concentration] through the semipermeable membrane.
Raisins and Prunes are grapes and plums that have been dehydrated. When placed in water, they begin to reabsorb the water that was previously removed, making them swell in size.
because when place in water ,water acts as a hypotonic medium so endosmosis takes place and raisins swell up
Because then go under Endosmosis.
because you are dum
when raisins are placed in concentrated solution of sugarthen they will swell up
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
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.
It is an example of hypotonic solution and the raisins will swell up.
Raisin imbibes water and swells up. Imbibition is actually absorption of water as raisins are dry, they take up water from hypotonic solution .
swell up and lyse
take up the water, swell
The raisins will swell up due to endososmosis.
There will be no change in the shape of the raisins since the concentration of solvent{most likely water} is equal in the interior and exterior parts of the cell. So no osmosis takes place since the solvent is already in the equilibrium.
Raisins sink in water because they are denser. However, the carbon dioxide molecules found in soda float to the top because they want to escape from the liquid. These CO2 molecules (seen as bubles) attatch to the raisins pulling them up to the surface as well. When the CO2 bubles reach the surface, they pop and the raisins begin to sink again.
Yes . Hope my answer helps!
Because they absorb the water they're in - which makes them swell up.
