(Question)
Use information from the paragraph to answer the question. Question: Kathy did some experiments on two different alkanes and one of the alkanes had twice as many carbon atoms than the other. She would notice that which alkane would require a lower temperature to melt alkane with fewer carbon atoms or alkane with more carbon atoms?? Paragraph : Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature.
(Answer)
alkane with fewer carbon atoms
