Answer 1

Answer:

when we put the resins in water and left it for 2 hour it will swell and when we put resins in salty water it will shrink

Explanation:

Resins have lower concentration of water then the outer surrounding so water move inside the cell(resins) and it gets swell

Whereas in case of salty water resins have higher concentration of water then the cell so water move out of the cell and it get shrink
