Where is the Gas Coming From?
Where is the Gas Coming From?
INVESTIGATING THE GAS IN OPEN AND CLOSED SYSTEMS
What did we do??
We put a bath bomb in a sealed bag and again in an open bag; we crushed both bath bombs to see if gas would escape from the bath bomb.
We also reacted bath bombs with water in a closed setting (sealed soda bottle) and an open setting (open soda bottle) to see if the gas was "new matter."
What have we proven so far??
We now know that the gas from the bath bomb was not trapped inside the bath bomb and was not "new matter." Instead, the gas comes from the substances that are there to begin -
the water and the bath bomb.
