(a) The theoretical temperature rise for burning a given mass of ethanol is 82.4°C. In the experiment the actual temperature rise for burning this mass of ethanol
was only 34.8°C.
One reason why the temperature rise is less than expected is that the ethanol
does not burn completely.
(i) Give a reason why, even if the ethanol burns completely, the actual
temperature rise is much less than the theoretical value.
