How do i know if its entering or leaving or neither just by the precentage?

1. Shrink

2. Swell

3. Neither

Explanation:

The percentage of water indicates how pure the water is, i.e. how concentrated the molecules of water are.

The higher the percentage of water, the more water molecules there are in the space.

Water molecules move from a high concentration to a low concentration across a semi permeable membrane, by the process of osmosis.

In beaker 1, the water outside is 89%, and inside the bag is 92%. That means the water inside the bag is at a higher concentration than outside. That means water will leave the bag, moving from a high concentration to a lower concentration outside. The bag will shrink.

In beaker 2, the water outside is 97%, and inside is 92£%. That means the water inside the bag is a lower concentration than outside. That means water will enter the bag, moving from a higher concentration outside to a lower concentration outside. The bag will swell.

In beaker 3, the concentration of water inside and outside is the same. That means they are in an equilibrium (the movement is balanced) so neither will occur
