states of matter

states of matter

1. solids

   • solids are hard
     • they have a fixed shaped
       • and are not compressible
         • because the particles are packed
           • closely together and cannot move
             • h20 ice= <0 degrees

2. liquids

   • have no fixed shape & are slightly compressible because
     • the particles are free to move compared to solid particles
       • h20 water= 0-100 degrees

3. gas

   • gas is very compressible &
     • takes the shape of whatever
       • container there're in therefore
         • they can move around more freely
           • h20 water vapor(steam)
             • >100 degrees

4. the 4 processes in water are

   • condensing
     • evaporation
       • freezing
         • melting

5. the difference between particles

   • is temperature
     • temperature is the measure of how hot or cold somthing
       • is and it is determined by the presence of heat energy
         • as you apply heat temperature increases
           • cold-low heat energy
             • hot- high heat energy

6. ice to water is melting

   • water to ice is freezing
     • water to water vapour is boiling
       • water vapor to water is condensation
