参考答案: Since
the alcohol evaporates more quickly, the alcohol molecules escape “easier” than
the water molecules. One explanation
could be that the intermolecular forces (bonds) for alcohol are smaller than
those for water. Another explanation
could be that the alcohol molecules are moving more rapidly than the water
molecules, indicating that alcohol molecules are less massive than water
molecules. However, the simplest alcohol
(C$H_3$OH) has a molecular mass higher than that of water, so mass is probably
not the explanation.
