Why can air be compressed and water cannot?

• Air particles are larger than water particles.
  

• Air particles are farther apart than water particles.

• Water particles are flexible.

• Water has no particles.
  

What of the following proves air is matter?

• Air is only a mixture of gases and not matter.
• Air is a gas and does not have weight.
• Air is invisible and cannot be measured.
• Air is matter because it occupies space and has mass.

When modeling the behavior of gas particles, what should be shown?

• Random motion and spaced gas particles.

• Gas particles only move in straight lines.
• Gas particles are still.

• Gas particles move the same way

 What happens when you push on the plunger of a capped syringe filled with air?

• The air inside the syringe is compressed, increasing pressure.
• The plunger gets stuck and cannot move.
• The syringe fills with liquid.
• The air expands, decreasing pressure.

What does a model of solid particles look like?

• A model of solid particles looks like scattered dots in a fluid.
• A model of solid particles looks like loosely arranged cubes.
• A model of solid particles looks like a single large circle.

• A model of solid particles looks like closely packed spheres.
