The Particle Model MD

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 description best matches this particle model?

• Closely packed and can't move a lot. 
• Particles are close together but can move a little. 
• Particles have lots of energy and can move around.
