Question

(a) Why is a high energy release per unit mass an important consideration in selecting a fuel for vehicles involved in transport, particularly air transport? b) How well do your results agree with these values?. (c) Comment on the main sources of error in this experiment and suggest how the experimental design could be improve. 5.(a) Graph the theoretical heats of combustion for each alcohol against the number of carbon atoms in each alcohol. b) Estimate a value for the heat of combustion of butanol. c) Use your data book to see how close your estimate for butanol is to the established value.

Results Table:
Initial Temperature for ethanol: 23 C, for
methanol : 22.5 C , for Propanol: 22.8 C
Mass of methanol: 229.36g, for methanol 227.27 g,
for propanol:227.9 g
Mass of ethanol used:1.92g, methanol used: 1.69g,
propanol used :1 g.
Final temperature: for ethanol:44C, methanol:43.2
C, propanol: 42.8 C.
