enthalpy change of combustion........

2007-03-24 7:06 am

我有日上堂做左個experiment,係用ethanol 同 butan-1-ol黎做...........
做完list左 table, table d data shows 用同等量heat d water, butan可以increase more temperature......但係點解既.......butan既bonding比ethanol多,應該要用多d energy to break bond 既..........但係點解唔係既.........

因為要寫report,佢有條question問 what will your prediction be for the enthalpy change of combustion for ethanol, butan-1-ol?
我唔知寫d咩好,因為之後重要support 個calculation......
唔該教下我la>

係fuel唔係fuse

參考: report 要自己做, 唔係考試實唔記得!
