Since Janice was given a mixture of alcohol and water, her teacher suggested that she use temperature to separate the two substances. The property demonstrated by the experiment is D. boiling. The boiling point refers to the temperature at which the liquid phase of the substance will turn into vapor. Water is known to boil at 100°C at atmospheric pressure while alcohols are generally known to have a boiling point lower than that of water. In this experiment, knowing that the two substances had a significant difference in boiling temperature was crucial to be able to separate them into their pure substances.
