Question: how does the heat of vaporization change with increased ethanol content?
Answer: An experimental study of the enthalpies of vaporization (also known as the heat of vaporization, the energy required to vaporize the entire liquid fuel) for ethanol/isooctane mixtures by Longfei Chen and Richard Stone at the University of Oxford found that the specific enthalpy of vaporization for an ethanol/isooctane ...
