Light up equal amounts and record which burns hotter and/or longer.

msds for iso alcohol shows auto-combustion temperature of 399 degrees C 50% iso will burn at a very low temperature (about 50 degrees celcius) - makes for a great science experiment - you can soak money in the solution, then ignite it, and the flame is cooler than the combustion temperature of money... The flame temperature depends on atmospheric oxygen, if you're vapourizing the iso first, etc...

IPA is less volatile and has a higher boiling point. On that basis I'd expect it tl burn more slowly. The temperature is somewhat meaningless, and best assessed by burning the stuff and finding out. L
