Nature of Matter

How do gases behave in a container?

• Cluster together
• form a solid
• They take the shape of their container
• leak out 

Which states allow easy flow of particles

• Gas and Solid
• Gas and Liquid
• Solid and Liquid
• Gas only

How do materials change from one state of matter to another?

• They gain or lose energy
• They break appart
• The particles get stickyer
• They are magnetised to themselves

What sorts of things are made of particles?

• Everything in the universe
• Anything solid
• Water 
• Most solids, liquids and gases. 

Can Solids be compressed?

• No
• Yes
• Sometimes (it depends what it's made of)
• Generally no

Which state of matter can be compressed?

• Solid
• Liquid 
• Gas

What happens to particles as they heat up?

• They slow down
• Nothing
• They don't move
• They speed up

Which state of matter has particles that move the least/slowest?

• solid

• water

• gas

Adding HEAT to matter causes its particles to:

• move faster and farther apart
• Move slower and farther apart
• Move faster and closer together
• Move slower and closer together

Which description best matches this particle model?

• Particles are closely packed, vibrate fixed position, strong intermolecular forces.
• Particles are closely packed, no movement, strong intermolecular forces
• Particles are closely packed, move around each other, medium intermolecular forces
