How will you show that air is dissolved in water?
Answer:
- Take some water in a container
- Heat the water
- Before the water begins to boil we see tiny bubbles in the container
- These bubbles have air dissolved in water.
To show that air is dissolved in water we take water in a pan and heat it.
Just before it boils, we will notice some bubbles at the inner surface of the pan.
These bubbles are formed because of air dissolved in water.
