question: Dana is testing alkanes to see how they boil. She first heats up alkanes with more carbon atoms, and then some with fewer. The alkanes with more carbon atoms have a boiling point, compared to the other, that is
choices.text: lower higher
choices.label: A B
para: Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature.
