The vapor of a flammable liquid won't explode in air unless it's above its "lower explosive limit" or "LEL." The LEL of gasoline in air is about 1.2% by volume (which is the same 1.2% of atmospheric pressure), and the normal boiling point of gasoline is about 99°C. At what temperature does gasoline reach its LEL? Assume that gasoline is actually isooctane, which has an enthalpy of vaporization of 35.16 kJ/mol.
