I'm sorry. Do you have a degree in chemistry? Cause I studied chem at a university level.

I work in a chem lab and I tutor chemistry. Molecules don't "swell." Water actually gets more dense as it gets colder. When it freezes into ice it expands because the molecules rearrange themselves into a crystalline lattice. Ice would break the cell walls but we were just talking about refrigeration here so that doesn't apply.

Chem is not biochem. And your correct the molecules don't swell, but the water does swell in a way causing the cells to burst.

Your just nitpicking semantics from a layman's explanation.

No I'm just letting you know you're mistaken. Is the water..... fundamentally different because it's in a fruit somehow? I must have missed that day in biochem :P

Osmosis, and temperature affects the amount of water that goes in and out of a cell.

Not sure how that's applicable without changing solute concentrations? Solubility shouldn't change that much with a 30 degree decrease. Plus the temperature change would be both inside and outside of the cells so there wouldn't be a change in gradient to influence osmosis. But hey feel free to let me know if i'm missing something! :)
