  1. what are the properties and uses of stainless steel
    • property - resistant to corrosion
    • uses - cooking utensils
  2. what are the properties and uses of hugh carbon steel
    • property - hard 
    • uses - drills , hammers , razor blades
    •  
  3. what are the properties and uses of low carbon steel 
    • property - easily shaped
    • uses - car bodies , wires , pipes , bicycles  
  4. smaller hydrocarbons 
    *
    *
    *
    *
    than larger hydrocarbons  
    • * have a lower boiling point 
    • * are more runny (less viscous)
    • * are more volatile (evapourate better)
    • * are more flameable  
  5. the hydrocarbons with lower boiling points evapourate at the 
    top and these are the shorter chained molecules 
  6. describe fractional distilation 
    • heat the crude oil to vapourise it 
    • the vapour rises up the column
    • then condenses at its boiling point 
  7. the order of the fractionaiting column from bottom to top is 
    • heavy fuel oil
    • bitumen
    • lubricating oil
    • diesel
    • kerosine
    • petrol
    • petroleum gases  
  8. bitumen is used for 
    road buildings 
  9. heavy fuel is used for 
    fuel for power stations and ships
  10. lubricating oil is used for
    lubricating engines 
  11. diesel is used for
    diesel fuel and heating oil
  12. kerosine is used for 
    heating fuel and jet fuel 
  13. petrol is used for 
    car fuel and making fuel
  14. petroleum gases are used for 
    gaserous fuels and making fuels 
  15. the longer the chain the ...... the ..... forces 
    • stronger 
    • intermolecular 
  16. shorter chains are more 
    useful than longer chains
