Fractional distillation of crude oil [CHEM]
點解 Fractional distillation of crude oil 係 physical seperation？
個答案話：Since it is not breaking the bond.
但呢個 seperation 唔係分開左 petroleum 架咩？
點解會 not breaking the bond？

petroleum係mixture of different hydrocarbons
separation 只係 overcome左components之間的intermolecular force 而唔係hydorcarbon之間個covalent bonding...
所以no new substance is formed 係physical changeSource(s): own knowledge
