Answer:
liquids with increasingly high boiling points.
Step-by-step explanation:
Alkanes are a type of chemical compound made up of carbon and hydrogen atoms. The size of an alkane molecule is determined by the number of carbon atoms it contains. Alkanes with a small number of carbon atoms, from 1 to 4, are in the form of gases at room temperature. Examples of these gases include methane, ethane, propane, and butane.
As the number of carbon atoms increases, alkanes become liquids with higher boiling points. Alkanes with 5 to 20 carbon atoms are generally found in liquid form at room temperature. Common examples of these liquid alkanes include pentane, hexane, heptane, and octane. They are often used as solvents in various industries.
When the number of carbon atoms exceeds 20, alkanes become increasingly thick and viscous liquids. At room temperature, they may even solidify and become waxy substances.
the smaller alkanes are gases, the medium-sized ones are liquids, and the larger ones are thick liquids or waxy solids at room temperature.
