WebNov 2, 2010 · The flammability DECREASES as the chain length increases. Methane (C1) is natural gas and by definition very flammable. C20 is basically paraffin wax and it will burn but with much greater difficulty. WebThe flammable limits reported are usually corrected to a temperature of 32°F (0°C) and 1 atmosphere. Increases in temperature and pressure result in reduced lower flammable limits possibly below 1 percent and increased upper flammable limits. Upper limits for some fuels can approach 100 percent at high temperatures.

WebAside from the intermolecular interactions, however, the melting point depends also on how the molecules are packed or arranged in the solid form. The more symmetrical they are, the better they pack and form a perfect crystal lattice which results in a higher melting point. WebDefinition: Homologs. Homologs are compounds that differ from each other by a repeating unit. We call this entire group of straight-chain alkanes the alkane homologous series. A homologous series is a family of compounds that have the same functional group, similar chemical properties, and the same general formula. how do i invest in cryptocurrency in canada
