Because water passes out of the raisins [region of higher concentration] into the salt solution [region of lower concentration] through the semipermeable membrane.
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
When raisins are soaked in water, they absorb the water and swell up, becoming plumper and softer. This process is called rehydration.
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.
If a cell is placed in pure water, the water will move into the cell through osmosis, causing it to swell and potentially burst. This process is known as cytolysis and can result in cell death.
The raisin swells in a hypotonic solution because there is a higher concentration of water outside the raisin than inside. This creates a concentration gradient that drives water into the raisin, causing it to swell as it absorbs water and increases in size.
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.
swell up due to osmosis, as water will move from an area of higher concentration (outside the cells) to an area of lower concentration (inside the cells), causing them to expand. This can eventually lead to the cells bursting.
