Answer:
Ethanol can be collected first, as it has the lowest boiling point among the three substances. Water comes next, followed by olive oil.
Explanation:
The boiling points of substances indicate the temperature at which they change from a liquid to a vapor. In this question, you've provided the boiling points for ethanol, water, and olive oil at different temperatures. To determine which one can be collected first, we need to compare their boiling points.
