16. Matter

The diagram shows the way that the particles in a solid occupy space.

Such particles are packed closely together and cannot move around, but they can vibrate.

Select the property of a solid from the list below, which is consistent with this micro-view of this state of matter.

• Cannot be compressed

• No definite volume

• Can flow

• No definite shape

The ability of the particles in a gas or liquid to move out and fill up all available space is called

• diffusion

• transfusion

• melting

• evaporation

Which one of the following diagrams represents the particles of melting ice?

• 
• 
• 
• 

The image shows how particles are arranged in a solid.

Which three of the following statements explains why solids have a definite shape?

• There is a strong force of attraction between the particles in a solid.

• The particles are arranged in a regular way.

• The particles in a solid are packed together very tightly.

• All of its particles have the same density.

• Particles in a solid can easily be compressed.

When particles in a solid are arranged in a regular pattern, they sometimes form what we call a

• crystal

• shape

• lump

• fluid

Which one of the following diagrams best represents a model of the particles in a solid?

• 
• 
• 
• 

Which change of state occurs when particles in a solid begin to move slowly past each other?

• Melting
• Boiling
• Condensing
• Subliming
• Freezing

The diagram shows the three different ways in which particles are arranged.

Which one of the following statements about the particle theory of matter is INCORRECT?

• All substances are made of the same particles.

• There are spaces between the particles of a liquid.

• All matter is made up of tiny particles.

• The particles can move when they are heated.

The photograph shows steam being released from an erupting volcano. Steam is a gas.

Gases consist of particles that

• are packed close together.

• are packed close together.

• are strongly attracted to each other.

• have a regular arrangement.

When two gases mix together, they are said to

• diffuse
• evaporate
• condense
• melt
