What analogies for osmosis?

Answer 1

An analogy for osmosis would be a crowd of people standing in a small room, there are a lot of people and they are uncomfortable. Some of the people will move to another room if there is another room and it is less crowded.

Answer 2

1. Osmosis is like a one-way street where only small cars can pass through but not larger vehicles, as it allows the movement of only water molecules through a semi-permeable membrane.
2. Osmosis can be compared to a sponge absorbing water, where water moves from an area of higher concentration to an area of lower concentration.
3. Osmosis is akin to a water balloon being filled up, with water moving into the balloon to equalize the concentration on both sides of the membrane.
