The molecules would move down towards the centre of the earth until stopped by something.
the water enters the potato's cell
When a potato slice/piece is placed in pure water, it gains mass and appears to be blown up. This is because the water is travelling into the potato because it has a lower concentration of water inside it.
the potato slice sucks in some of the water. that how it gets soggy
no.it contains starch...
This process is called osmosis. I.e the movement of water across a semi-permeable membrane from an area of high water concentration to an area of low water concentration. When dipped in water the water moves into the potato. Such a solution is called a hypotonic soln in which potato becomes swollen.
you have to slice it first then it will shrink
In the salt solution the concentration of water inside the cells of the potato is higher than that outside. Therefore water molecules move from inside the potato where there is higher concentration of water molecules to outside the potato where there is a lower concentration of water molecules through semipermeable membrane of the potato cells. This process is called osmosis.
Beacause when you put the slice of potato in water osmosis takes place since concentration of water is lower then the concentration of the potato and water moves from ow concentration to high concentration so the water will move into the potato and the potato will become ridgid, But if you put salty water the salty water has a higher concentration then the potato so water will move out of the potato and the potato becomes soft.
A patato cube is placed in a beaker filled with hot salt water and another patato cube is placed in a beaker filled with cold salt water?
water willl leave the cucumber
vacuole
It gets softer.
No a potato will not get heavier if placed in salt water, and does it really matter if it does? Do not ask stupid questions. Keep it simple.
