Understanding States of Matter

What is the main difference between the particles in a solid and a liquid?

• Particles in a liquid are far apart and move freely.

• Particles in a solid are close together and vibrate in fixed positions.

• Particles in a liquid are very close together and do not move past each other.

• Particles in a solid are far apart and not attracted to each other.

How do particles in a gas behave compared to those in a liquid?

• Gas particles are closer together and vibrate in place.

• Gas particles are very attracted to each other and move past one another.

• Gas particles are far apart and not very attracted to each other.

• Gas particles are tightly packed and do not move.

What happens when you squeeze a bottle filled with air?

• The particles of air move closer together.

• The particles of air move further apart.

• The particles of air disappear.

• The particles of air remain in the same position.

How do the particles in a gas differ from those in a solid?

• Gas particles are very attracted to each other and move past one another.

• Gas particles are tightly packed and do not move.

• Gas particles are very close together and vibrate in place.

• Gas particles are far apart and not very attracted to each other.

What is the significance of the animation showing particles moving from a bottle into a balloon?

• It shows that air particles can move and inflate a balloon.

• It demonstrates that air is not made of particles.

• It indicates that air particles are immobile.

• It proves that air particles are visible.

Why is it difficult to compress a liquid compared to a gas?

• Liquid particles are not attracted to each other.

• Liquid particles are very attracted to each other and move freely.

• Liquid particles are close together and almost incompressible.

• Liquid particles are far apart and can be easily compressed.

What concept is illustrated by the difficulty in compressing water in a bottle?

• Water particles are very attracted to each other and move freely.

• Water particles are close together and almost incompressible.

• Water particles are far apart and easily compressible.

• Water particles are not attracted to each other.

What does the example of the girl on the diving board illustrate about solids?

• Solids have particles that move past one another easily.

• Solids have particles that are far apart and move freely.

• Solids have particles that are close together and vibrate in place.

• Solids have particles that are not attracted to each other.

In the context of NGSS standards, what is emphasized about matter?

• Matter is made of large, visible particles.

• Matter is made of particles that are always visible.

• Matter is made of particles too small to be seen.

• Matter is not made of particles.

What is the primary focus of the NGSS performance expectation v PS 1:1?

• To develop a model showing that matter is made of large particles.

• To develop a model showing that matter is made of visible particles.

• To develop a model showing that matter is made of particles too small to be seen.

• To develop a model showing that matter is not made of particles.
