Marissa blows up balloons for a party. She decides how big or small to make each balloon. Why does the air she blows into each balloon take up all the space inside the balloon?

• The particles of air move around and slide past one another and take the shape of the balloon.

• The particles of air move freely, colliding with each other and the sides of the balloon.

• The particles of air move and increase in size when they have more space in the balloon.

• The particles of air have a strong attraction between each other and the balloon.

Which model represents the attractive forces in a liquid?

• Model 3 represents a liquid because the particles are hardly affected by the attractive forces.

• Model 2 represents a liquid because the attractive forces keep the particles vibrating in place.

• Model 1 represents a liquid because the particles are locked in their positions because of the attractive forces.

• Model 2 represents a liquid because the attractive forces keep the particles close together but still allow movement

At room temperature, aluminum is a solid and water is a liquid. How do the particles of solid aluminum compare to the particles of liquid water?

• The attractions between the particles are weaker in the solid aluminum.
• The attractions between the particles are stronger in the solid aluminum.
• There is no attraction between particles in the solid aluminum.
• The particles are moving more freely in the solid aluminum.

Raul and Bonnie are trying to classify several objects that they found during a field trip to the beach. They collected a sample of seawater, a piece of driftwood, and several smooth pebbles. How are the particles that make up the driftwood different than those of the pebbles and the seawater?

• The particles vibrate, but stay fixed tightly together
• The particles do not vibrate and they stay fixed tightly together.
• The particles vibrate and frequently collide, but stay close together
• The particles vibrate and frequently collide, but move freely in all directions.

Which statement below best describes the movement of particles in a gas?

• The particles do not move.
• The particles move freely.
• The particles vibrate in a fixed position.
• The particles slide easily past one another.

Why does liquid water take the shape of the cup it is poured in to, but solid ice cubes do not?

• Because the particles of liquid water are softer than particles of solid ice.
• Because the particles of liquid water are smaller than the particles of solid ice.
• Because the particles of liquid water are moving but the particles of solid ice are not.
• Because the particles of liquid water can easily move past one another but the particles of solid ice cannot.
