|
Flash point
|
Is the min temp at which a liquid gives off enough vapors that will ignite and flash over but will not continue to burn without additional heat.
|
|
Fire point
|
Is the temp at which a material produces sufficient vapors that, once ignited by an outside ignition source will continue to burn.
|
|
Volatility
|
measures how easily a liquid or solid can pass into a vapor state.
