fas

good thinking, but will it satisfy my chem teacher?.........

I have a problem that i can't solve myself, so i am thrusting it on all others---- There are a mixed a number of kerosene and water barrels left outside a workshed. You cannot see inside the barrels, nor can you move them... Is there any way of telling which barrels contain kereosene and which contain water?

yup thanks, that answers everything

yes, but could u go deeper

I have heard an interesting question somewhere, but i haven't been able to find a suitable answer. Could anyone tell me what a flame is?
