Question

select the correct answer. chantal was eating raisins and a few of them fell into her glass of drinking water. she finished eating the rest of the raisins. when she went to dump out the water in her glass, she observed that the raisins had become swollen. why would this have happened? a. the water content from the raisins moved into the glass of water. b. the water in the glass entered the raisins. c. the grapes used for making the raisins werent properly dried. d. the raisins were bad - quality raisins and therefore were swollen.

Explanation:

Raisins are dried grapes with a lower water concentration than the surrounding drinking water. Through the process of osmosis, water molecules move from an area of higher water concentration (the glass of water) to an area of lower water concentration (inside the raisins) across a semi - permeable membrane (the raisin's skin). This causes the raisins to swell as they take in water. Option A is incorrect as water doesn't move out of raisins into water in this case. Option C is incorrect because the swelling is due to osmosis, not improper drying in a way that would cause this immediate swelling in water. Option D is incorrect as the swelling is a normal osmotic process, not due to bad - quality raisins.

Answer:

B. The water in the glass entered the raisins.
