Answer 1

Answer:

observation :

before: the potato pieces were having original shape.

after sprinkling salt :they lose their shape because of lose of water.

after putting into water : they regain their shape and come back to their original size .

REASON: OSMOSIS

Explanation:

Osmosis is the process of movement of water from higher concentration to lower concentration accross the semi permiable membrane . It also depends on the amount of solute present in water if there is more amount of solute present in water( solvent)it becomes a concentrated solution ( hypertonic solution ) but if there is more amount of solvent present instead of solute , concentration of water is more( hypotonic solution)

as per the question's situation when we sprinkle salt on potato , concentration of water increases inside and potate will lose water outside accross the membrane because of which it shrinks . As you put it into water it gains water as concentration of water increases outside and the pieces take their original shape
