  • Definite Volume (CanNOT be compressed)
  • Solids like sugar dissolve in water = soluble

# Gases

  • No Definite Shape(Takes up the shape of a container)
  • No Definite Volume(Can be compressed)
  • Can be useful (e.g.Oxygen,Carbon Dioxide,Water Vapour) and harmful(e.g.Carbon dioxide,Sulphur dioxide)

Changes Of States

Solid(melting)=> Liquid (evaporates)=> Gas

Gas(condensation)=>Liquid(freezing)=>Solid(Sumblimation)=>Gas
