C. The boiling point of pure ethyl alcohol is 78.3 at 760 mmhg. Would the boiling point of alcohol be higher or lower than 78.3 at higher altitude? Why?
The boiling point of alcohol would be lower at higher altitude. This is because at higher altitudes, the atmospheric pressure is lower than at sea level. The boiling point of a substance is directly proportional to the atmospheric pressure, meaning that as the pressure decreases, the boiling point also decreases. Therefore, at higher altitudes where the atmospheric pressure is lower, the boiling point of ethyl alcohol (and any other substance) will be lower than at sea level.
