Fire point: a temperature at which a liquid produces vapors that will sustain combustion (several degrees higher than a ashpoint) 1. liquid that has a ashpoint higher than 100f: flammable liquid. 1. liquid that has a ashpoint under 100f. Heat: energy possessed by a material due to molecular activity. 1. transfer of heat through direct contact: convection. 1. transfer of heat through circulation: radiation, emission o energy rays or waves, arson. A. the criminal act of deliberately setting re to a property with the intent to cause damage.
