Everything is made of elements. What elements could be in the gas that
forms when sodium bicarbonate (NaHCO3) and citric acid (C6H807) react?
•Sodium (Na)•Hydrogen (H)
•Oxygen (O)•Carbon (C)

What gas do you think is in the
bubbles that form when NaHCO3 and
C6H807 react?

What is air?•How do you know when something is a gas?
•What is gas made of?•How do you know when something is matter?
•Is gas matter?

Syringe system
•Work alone with one system or with a partner using two
•Clamp the tubing with the binder clip
•Work with or without air in the syringe

•Does air take up space?
•What is your evidence?
•Does air always take up the same amount of space?

•Gases in air have mass and occupy space
•Therefore air isMATTER

Compression•Air can be forced into a smaller space
•Air that is forced into a smaller space is called COMPRESSED air
![Page 11: Investigation 3 2 air is matter 2010](https://reader035.fdocuments.net/reader035/viewer/2022062319/5563ba12d8b42a38198b5199/html5/thumbnails/11.jpg)
When the force is removed, the air
EXPANDS and occupies more
SPACE

Particulate Model
•Air is composed of particles too small to see
•Particles are in constant motion
•There is SPACE between the particles of air

Reflection page 24•Using what you know about the particulate model, illustrate a gas that has been compressed and one that has been expanded
