Simple Classification of Substances and Separation of Mixtures: Separation of liquid-gas mixture
2.0 Simple Classification of Substances and Separation of Mixtures
2.9 Separation of liquid-gas mixture
Once more, view the earlier demonstration of dust particles suspended in hot water.
But this time, observe the bubbles that are stuck on the wall of the plastic jar, not the movements.
Questions 2.9 
- From the demonstration, what is the evidence that water contains dissolved air?
- How does an increase in temperature affect the amount of gas dissolved in a liquid?
- How can we remove gases dissolved in water (or any liquid)?
- How can we obtain dissolved gases from their solutions in water?
