1. Which statement best identifies the movement of the particles in a liquid? (SC.8.P.8.1.)

• The particles of a liquid move freely.

• The particles of a liquid slide past each other.

• The particles of a liquid vibrate and barely move.

• The particles of a liquid do not move at all.

1. Which statement best identifies a solid? (SC.8.P.8.1.)

• Particles barely move and are tightly packed.

• Particles barely move and are farther apart.

• Particles move more quickly and are farther apart.

• Particles move more quickly and are tightly packed.

1. Which statement best identifies which of these models is a liquid? (SC.8.P.8.1)

• Diagram A is a liquid, because its particles move the slowest and are tightly packed.

• Diagram B is a liquid, because its particles move at a medium speed, and are sliding past each other.

  C.

• Diagram C is a liquid, because its particles move the fastest and bounce all over the place.

• Diagram A and B are both liquids, because the particles are always touching.

How does the picture relate to the particles in a solid?

• The cars are driving fast and switching lanes like the particles in a solid.

• The cars are sliding past each other while driving the speed limit like the particles in a solid.

• The cars are moving so fast you cannot even see them like the particles in a solid.

• The cars are barely moving like the particles in a solid.
