Donna and dave were participating in a lab on the properties of water. first, they tried to see how many drops of water they could fit on a penny. then they dropped water and alcohol on waxed paper and observed what happened. next they made a streak of water and then alcohol on the lab bench. the alcohol streak dried up and disappeared first. donna and dave had to write an explanation for everything that happened during the lab. how can they explain the disappearing alcohol?

the answer is B, Alcohol has a lower boiling point than water i know this is the answer because i did USA TEST PREP and it was correct

B)Alcohol has a lower boiling point than water.

Explanation:

Alcohol has a lower boiling point than water. Because of this, alcohol will turn into a gas, or evaporate, much faster than water. That's why it seemed to disappear faster than water; it evaporated or turned into a gas faster.
