Question

Garima observed that when she left her tightly capped bottle full of water in open sunlight, tiny bubbles were formed all around inside the bottle. Help Garima to know why it happened?

Answer 1

Reason for the formation of tiny bubbles inside the bottle:

1. When the water warms to the atmospheric temperature, most of the air dissolved in water comes out of the water.
2. Then the equilibrium between gas molecules leaving and joining the air or water interface becomes unbalanced.
3. When this occurs, bubbles are formed from the gaseous molecules of water vapor which float to the surface of the bottle.
4. This process can be seen in bottles or any other cups and glass too.
