Grade 7 Agenda:

SLANT: STATES OF MATTER, KEY CONCEPTS

THE FOUR STATES OF MATTER

  • GASES
    • definition
    • properties (compressible, expands, diffuses)
    • particle arrangement
    • particle motion
    • Relationship between the state, number of particles, pressure, and temperature

SLANT: States of Matter Simulation

PhET: States of Matter

 

Use the simulation to explore the questions listed below.  copy the question and summarize your findings in your science notebook.

The simulation starts with a solid.  Use the "hand" to press the lid down.

1) Can you compress (squeeze) a solid into less space?  How does attempting this affect temperature and pressure? (Explain what you find.

 

Use the heat/cool control to create a gas. 

2) How do you know when a gas has been created? What do you have to do to make a substance become a gas?

 

Experiment with the "bicycle pump." 

3) How does adding more particles to the container affect the temperature and pressure?

 

Press on the gas using the "hand." 

4) How does pressing on the gas affect the temperature and pressure?

 

Reset the simulation.  Use Neon.  Heat it to exactly 40 deg. K.

Make a data table that records temperature and pressure. Be sure record the units.

Use the hand tool to compress the gas in small increments.  Record the temperature and pressure in at least 10 separate positions.  Do not blow the lid. If you do blow the lid, reset the simulation and start over.
