question: John was playing with alkanes in his lab. If he decreased the amount of carbon atoms in an alkane, what would happen to the boiling point of that alkane?
choices.text: decrease? increase
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.
