Question

The grape wrinkles if kept in saltwater because of

Answer 1

Answer: When you add enough salt, the water can become denser than the grapes. Therefore, grapes can float in the saturated salt water.

Explanation:

Answer 2

The reason is 'Osmosis.'

• Osmosis is the movement of the solvent from its area of higher concentration to a lower concentration through a semi-permeable membrane.

• The grape has a higher concentration of water in it. The saltwater has a lower concentration of water due to the presence of the solvent salt.

• Thus, when the grape is placed in the saltwater, water moves from its area of higher concentration in the grape to its area of lower concentration in the saltwater. The skin of the grape is the semi-permeable membrane.

• Due to the ejection of water, the grape wrinkles.
