Indicate which of the following processes are physical processed and which are chemical processes A)Corrosion aluminum metal B) Cutting a diamond C)Burning gasoline D) Boiling water
A chemical process will change the chemical composition of something, whereas physical only changes the arrangement of molecules of it, so:
A) Corrosion of aluminum metal- chemical: this is "rusting" caused by oxidation
B) Cutting a diamond-physical: there is no chemical change made here, just a separation of moecules
C) Burning gasoline-chemical: gasoline reacts with oxygen to form water and carbon dioxide
D) Boiling water-physical: this makes the molecules move faster and farther apart
