    The previous answer about proteins being denatured is quite correct. But I guess, the answer for this question at the most basic level is this.

    Boiling effectively destroys the cell membrane, hence you end up with strips which are very flaccid, ready to be mashed. When you immerse it into the salt solution, the potato will remain the same because the cell membrane is not present anymore for osmosis to occur. The salt solution will just penetrate through, while the cell liquid contents will just spill out across the fully permeable cell wall. As such, no osmosis will occur, but simple diffusion of substances will just happen. If you test it, the solution in an out of the boiled potato strips would have been very similar after a while.

    What's the concentration of your salt solution? But, regardless... this is what generally should happen, if I'm not mistaken. Hurrah, osmosis! (Heh.)

    Boiling the potato strip for 10 minutes means that you're basically immersing it in water, which as we all know is hypotonic to potato strip cell sap. This means it'll become firm and absorb the water, with the rate of water entering the cells of the potato strip being higher than the rate of the potato strip's cell sap diffusing out of the cell and into the boiling water.

    Now, salt solutions are hypertonic to the potato strip's cell sap. After you're done boiling that poor potato strip and you place it inside the salt solution, the potato strip'll become flaccid. The water molecules inside the cell sap diffuses out into the salt solution at a higher rate than the rate of the water molecules of the salt solution diffusing into the cell sap inside the cells of the potato strip.

    Aaaaaaand you also get a salty potato strip, if that helps. ;) If anything, the heat/temperature of the potato strip should encourage the absorption of the salt solution by the potato strip, so... I'm also assuming that boiling the strip for 10 minutes rather than just placing it in water of room temperature was to speed up the osmosis reaction of the potato strip towards the water, but... I don't know about that. 8D Eheh.

    Edit: I knew I missed something! Do refer to the answer below to find out what happens to the membranes of the potato strip when you boil it. It's quite crucial.

    Boiling the potato would denature many of the proteins its cell membrane. This would disrupt the continuity of the membrane, making it "leaky."

    In a hypertonic solution, water from inside of the potato cells would diffuse out, thus resulting in shriveled up cells.

    I don't see how this would be any different than not boiling the potato, unless membrane integrity was maintained and the aquaporins were denatured...preventing the movement of water.

    It would then be stuck under a light bulb to cook

    and then placed in a mc donalds container

    soggy fries

    I think it will increase in size
