#Fire Point:- 

The lowest temperature at which the vapor of that fuel will continue to burn for at least 5 seconds after ignition by an open flame.

#Smoke Point:-

#Pour Point:-

The lowest temperature at which the oil will pour or flow when it is cooled without stirring.

#Boiling Point:- 

The temperature at which the vapor pressure of a liquid is equal to the pressure of the atmosphere on the liquid.
