Explain the difference between flash point and fire point?
Flash point is the temperature at which a flash will occur across the face of a liquid and go out. Fire point is the temperature at which a flash will occur above the liquid and the resultant fire will continue to burn.
How can the boiling point of a liquid be raised without adding soluble impurity?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, or the pressure above the liquid. So, to increase the boiling point without adding a solute, one can increase the pressure above the liquid.
What does it mean if the flash point of a liquid is more?
Flash Point is a carefully defined feature. It is the temperature at which the vapour of a volatile liquid will ignite to form an ignitable mixture in the presence of an ignition source. When the ignition source is removed, the combustion may well cease. And of course, when the word MORE is used, there must be a second material/property with which it is to be compared.
What liquid is known to have a flash point of 98 degrees F?
Gasoline is known to have a flash point of 98 degrees Fahrenheit. This means that the liquid releases enough vapor to ignite in the presence of an ignition source at that temperature.
What does the flash point of gas mean?
When gas flashes it should be arrested for indecent exposure. This happened to me once. It was a nasty point of my life. The above answer is silly! The flash point of a volatile liquid is the lowest temperature at which it can vaporize to form an ignitable mixture in air. Measuring a liquid's flash point requires an ignition source. At the flash point, the vapor may cease to burn when the source of ignition is removed. The flash point is not to be confused with the autoignition temperature, which does not require an ignition source.
What is the definition for flash point and smoke point?
In a Nut ShellFor any flammable liquid, its vapor pressure maximizes with increase in temperature.Flash point is the lowest point at which the vapors of a liquid ignite but stops on removal of an ignition source.Fire Point or ignition point is basically a point above the flash point at which burning will continue on removal of the ignition source
What does 'Have a point' mean?
The flash point is the lowest temperature at which vapors of a liquid can ignite.

How do you increase the flash point in diesel oil?
A low flash point in diesel is caused by contamination of the diesel with lighter petroleum products such as kerosene or gasoline. Drawing more lighter products out of the fractionation tower could reduce contamination of the heavier products. Improving fractionation and improving diesel product stripping performance will raise the flash point.
What liquid is known to have a flash point of 98 degrees F?
Gasoline is known to have a flash point of 98 degrees Fahrenheit. This means that the liquid releases enough vapor to ignite in the presence of an ignition source at that temperature.
When is an unlisted liquid flammable solvent classified as HW?
Flash point of 21 C or below
Why is liquid cooling system pressurised?
to increase the boiling point of the coolant

What is the term for the lowest temperature at which a liquid produces enough vapor to sustain a continuous fire?
flash point
What is significance of flash point?
The flash point of a flammable liquid is the lowest temperature at which it can form an ignitable mixture in air. At this temperature the vapor may cease to burn when the source of ignition is removed. A slightly higher temperature, the fire point, is defined as the temperature at which the vapor continues to burn after being ignited. Neither of these parameters is related to the temperatures of the ignition source or of the burning liquid, which are much higher. The flash point is often used as one descriptive characteristic of liquid fuel, but it is also used to describe liquids that are not used intentionally as fuels
