Matter Exists in Different States (G7U2L2)

Which model best represents the particles in a solid?

• Model A

• Model B

• Model C

• Model D

Which statement best describes the level of attraction between particles in a liquid?

• Particles are not attracted to each other at all.

• Particles are slightly attracted to each other, but their kinetic energy prevents them from sticking together.

• Particles are moderately attracted to each other, allowing them to slide past each other.

• Particles are strongly attracted to each other, causing them to vibrate in place relative to each other.

Why is a gas able to expand to fill its container?

• Gases cannot expand and always remain in a fixed volume.
• The particles in a gas have a lot of kinetic energy, causing them to spread out rather than stick together.

• The particles in a gas are attracted to each other and to the container walls.

• none of these
