cheers thanks for that site, im checking it out now.

I found it!! i got all the info on molar heat of combustion!! so stoked. but it says that while methanol, 1-propanol and 3-pentanol release consecutively more heat, 1-hexanol releases less than 3-pentanol rather confusing but ill run with it. Any idea how much heat it takes to raise the...

Thanks for those two, that is a start. yea i think im gunna try and "borrow" my chem teachers data book. or he might even let me who knows. such a strange task...

hmm Yea i figured as much that it gets bigger as you go along. thanks for the equation bit i completely forgot about doing that. do u have any idea where i can get the actual data for the heat of combustion? im all out of ideas, all i can think of is to but a data book....

Hi, i have a research task in which you have to assess which of four given alcohols would (best) keep you alive for four days if u only had one litre of each... you have to account for the Molar heat of combustion, the amount of CO2 gas produced, and weather it combusts completely (ie how...
