Answer the question below:   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 higher temperature to melt alkane with fewer carbon atoms or alkane with more carbon atoms??    Assuming that:  Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature.
alkane with more carbon atoms?
