Discussion
Demonstrates a chemical change
Discussion (con.)
physical properties before- liquid
physical properties during- liquid
physical properties after- gas
Discussion (con.)
Phase changes of chemicals
starts as a liquid
heat caused- phase change
Discussion (con.)
Chemical properties before- combustible
chemical properties during- burning
chemical properties after- water
Conclusion
answer: whoosh bottle was chemical change
hypothesis: support because fire shows its a chemical change
Real Life Example
Cylinder firing in a rocket. Has same heat as the whoosh bottle does
