T2_Lesson 2: Particle Model of Matter

What is the main focus of the Particle Model of Matter?

• The volume of gases

• The particles and their interactions

• The states of matter

• The temperature of substances

How many rules are there in the Particle Model of Matter?

• 10

• 7

• 5

• 3

What do we call the forces that keep particles together?

• Gravity

• Repulsion

• Attraction

• Friction

What is true about the spaces between particles?

• They are filled with energy

• They contain liquid

• They are empty

• They are filled with air

What happens to particles when temperature changes?

• They become invisible

• They change their motion

• They change their arrangement

• They stop moving

What is the state of motion of every particle in a substance?

• They are always at rest

• They are always in motion

• They only move at high temperatures

• They move only in solids

What does the Particle Model of Matter help us to do?

• Measure the weight of particles

• Create new substances

• Identify different states of matter

• Make predictions and do calculations

What is the main cause of changing the motion of particles?

• Pressure

• Temperature

• Volume

• Mass

What do we study in the Particle Model of Matter?

• The arrangement and interaction of particles

• The chemical reactions

• The color of substances

• The density of liquids

What is the difference between the Particle Model of Matter and the general States of Matter?

• The states of matter are more complex

• There is no difference

• The Particle Model focuses on particles, while states focus on visible substances

• The Particle Model is only for gases
