Flash Point of Different Liquids
The flash point of a liquid is the lowest temperature at which it can produce enough vapor to ignite in the presence of an open flame or spark. It is a crucial safety parameter, as liquids with lower flash points are more volatile and pose a higher fire hazard.
The following table provides a comprehensive list of flash point values for various liquids under 1 atmospheric (atm) pressure.
