Liquid pressure: A liquid's boiling point rises in proportion to its liquid pressure. Length of the chain: A liquid's boiling point increases with a long carbon chain. The boiling point rises as a result of the increasing attractive force that occurs with molecule length.

Given that methanol and ethanol have very high auto ignition temperatures (AITs) of 470 °C and 365 °C, respectively, it seems unlikely that hot surfaces in the absence of a flame served as the igniting source.

roughly 1% to 10% "Since many popular solvents have a flammable range of only 1% to 10%, it would seem that they are safer than chemicals with a much wider range.

Relative boiling points can be predicted using intermolecular forces (IMFs). The substance's boiling point and vapor pressure increase with the strength of the IMFs.

The flexible group of fast to medium evaporating aliphatic hydrocarbon fluids known as Shell Chemicals' specific boiling point (SBP) solvents includes paraffins and cycloparaffins in the C6–C10 range.

Air pressure has a direct impact on a liquid's boiling point. The weight of the air molecules pressing down on the liquid equals this pressure. We call this atmospheric pressure in an open system. Liquids need more energy to boil at higher pressures, and their boiling points rise accordingly.

When the vapor pressure of a liquid or solution reaches the applied or external pressure (usually the atmospheric pressure), boiling begins. The liquid's boiling point will therefore drop if the applied pressure is decreased.

Extending the response from earlier, the partial pressure of the hydrocarbon signifies the percentage of vaporized hydrocarbon.
