Solids Liquids Gases

Why are gases easier to compress than liquids

• They are less dense

• Their particles are held together less tightly

• Their particles are further apart

• Their particles move randomly

What do carrots, lemonade and air have in common?

• They all have mass and occupy space

• The particles move randomly

• They are composed of identical particles

• They are coloured

What is a consequence of the particles in liquids being able to roll over one another?

• They cannot be compressed

• They can be poured

• They diffuse quickly

• They expand when heated

Which choice correctly identifies each kinetic theory diagram?

• Solid, liquid, gas

• Gas, solid, liquid

• Liquid, gas, solid

• gas, liquid, solid

What causes particles of matter to move faster?

• Weaker forces between them

• Heating the matter

• Cooling the matter

• Shaking the matter

What happens to the particles of matter when it expands?

• They get larger and occupy mor space

• They get hotter and increase in volume

• They break the forces holding them together and spread out into a larger volume

• They move faster, collide more violently, and need more room to move in

Between which particles would you expect the forces to be the strongest?

• Between air particles

• Between water particles

• Between ice particles

• Between steam particles

Consider the diagram. Which label identifies R?

• Evaporation

• Condensation

• Melting

• Freezing

Considering what you know about lipstick, which statement is correct?

• Forces between lipstick particles and lip particles are stronger than those between lipstick particles

• Forces between lipstick particles are stronger than those between lipstick and lip particles

• Forces between lipstick particles are equal to those between lipstick and lip particles

• Forces between lipstick particles are equal to those between lip particles

Which diagram correctly shows the particles of a gas in a closed container?

• A

• B

• C

• D
