Properties of Matter

Solids

• Particles in solids don't move and don't fill a space - they have a definite volume
  
• Can always be seen, except for those that are too small or transparent for the naked eye
  
• Have a definite shape
  

Liquids

• Particles in liquids flow and fill the space they're in, following the rules of gravity - they have an indefinite shape
  
• Can always be seen, except for those that are too small, transparent, or soaked into a solid for the naked eye
• Assuming good health conditions, that you are trying to feel it, and that there's enough of it, we can always feel liquids
  
• Have a definite volume
  

Gases

• Particles in gases flow and fill the space they're in, ignoring the rules of gravity - they have an indefinite shape
  
• We can rarely see gases, except for when the particles are big enough like steam and our breath in the winter
  
• Have an indefinite volume
