How do the particles of a gas move?
Create an analogy of how gas particles move.
The particles of a liquids move like a bunch of students coming through the front doors of school. They are close together, collide and move past one another.
Question: How does the pressure exerted on a syringe affect the volume of the air inside it?
Research: (you need to define these words for the research section) Define these words
Hypothesis: If books are stacked on a syringe filled with air, then __________________ because ___________________________.
- Plastic syringe
- Modeling clay
- 4 science textbooks
- Lift the plunger of the syringe as high as it will move without going off scale.
- Seal the small opening of the syringe with a piece of clay. The seal must be airtight.
- Hold the syringe upright with the clay end on the table. With help from a partner place one science book on the top of the plunger.
- With the book positioned on the plunger, read the volume shown by the plunger and record in data table.
- Place another book on top of the first book. Record new volume in the data table.
- One by one, place each of the remaining books on top of the plunger. Record.
- Remove the books one at a time and record the volume of the syringe in the data table after each book.
