Solid, Liquid & Gas

• Solids, liquids and gases


  • They are all pictures of water, so they have the same types of particles
  • They are in different states of matter. 1 is a solid, 2 is a liquid and 3 is a gas
• How to get from picture 1 to picture 2


  You can get from ice (solid) to water (liquid) by melting
• States of matter


  • Solid
  • Liquid
  • Gas
• In each state, the particles are the same, but the way they're arranged changes
• Objects sorted into states of matter


  • Solid: Crayons, Books, Cheese, Ice
  • Liquid: Ice cream, Hot chocolate, Puddle, Paint, Drink, Milk
  • Gas: Steam, Wind
• There are three different states of matter: solids, liquids and gases
• Water can exist in all three of these states as ice, liquid water and steam
• In the different states, the particles of water are identical but the properties of the states are different
• This is because of the way the particles are arranged
• Solid


  • Have a fixed shape and cannot flow
  • They cannot be compressed (squashed)
• Liquid


  • They flow and take the shape of the bottom of their container
  • They cannot be compressed (squashed)
• Gas


  • They flow and completely fill their container
  • They can be compressed (squashed)
• Reason for properties of states


  • The particles can move around each other
  • The particles cannot move from place to place
  • The particles are close together and have no space to move into
  • The particles are far apart and have space to move into
  • The particles can move quickly in all directions
• The gaps between particles in a gas do not contain air
• Liquids and gases take the shape of their container because the particles are free to move around because there are weak forces between the particles
• Solid and liquids can be squashed as the particles are not very hard
• Particles in a gas move randomly and at high speed
• Particles in a solid do not move around as the forces between the particles are very strong
