Understanding the Particle Model of Matter

What does the particle model of matter explain?

• How matter is created

• How particles are arranged and move within different states of matter

• Why substances change color

• The chemical reactions between substances

What is the main difference between the states of matter?

• The color of particles

• The arrangement, energy, and interaction of particles

• The shape of particles

• The number of particles in each state

Which of the following is true about all matter?

• All matter is made up of particles

• Only gases are made up of particles

• Liquids are not made up of particles

• Solids do not contain particles

How does temperature affect particles?

• It changes the size of the particles

• It affects the speed at which particles move

• It turns particles into new substances

• It causes particles to disappear

What happens to particles in a gas?

• They stay close together

• They move slowly and vibrate in place

• They move rapidly with large spaces between them

• They lose energy and stop moving

What state change occurs when a liquid turns into a gas?

• Freezing

• Condensation

• Boiling

• Subliming

Which process describes a gas turning into a liquid?

• Melting

• Freezing

• Condensing

• Boiling

What happens to the particles in a solid when it is heated?

• They move slower

• They stop moving

• They gain energy and vibrate faster

• They disappear

In which state of matter are particles closest together?

• Gas

• Liquid

• Solid

• Plasma

What occurs during the process of sublimation?

• A gas turns into a liquid

• A solid turns directly into a gas

• A liquid turns into a solid

• A gas turns into a solid
