Freezing point of alkanes

WebNotice that when the molecular mass of the alkanes is low (i.e. there are few carbon atoms), the organic compounds are gases because the intermolecular forces are weak. As the number of carbon atoms and the molecular mass increases, the compounds are more likely to be liquids or solids because the intermolecular forces are stronger.. The larger a … WebJet-A (POSF-10325) is composed of on average 32 wt% total cycloalkanes (mono and bicyclic alkanes) (Holladay et al., 2024). If cycloalkanes are blended into Jet-A at 10 or 30 wt%, the cycloalkane content of a typical fuel increases from 32 wt% to 40 or 52 wt%, respectively. ...
