Quizplus · Accepted Answer

The thermodynamic parameter given is the normal boiling point of ethanol, which is defined as the temperature at which the vapor pressure of the liquid is equal to the external pressure. The normal boiling point of ethanol is 78.37°C or 173.13°F. Among the given choices, D) 69°F or 20.56°C is closest to the actual boiling point of ethanol. Therefore, the best choice is D).
