i think dew point.
The dew point is the varying temperature at which atmospheric humidity condenses. If the air temperature drops below the dew point, dew and condensation form.

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.
I'm not sure how you arrived at this conclusion, but it's incorrect. The flash point is defined as " the lowest temperature at which it can vaporize to form an ignitable mixture in air" - this temperature remains the same regardless of location.
oiling PointBoiling point is a property of a liquid. The boiling point is defined as the temperature, where the vapor pressure of the liquid is equal to the external pressure on the liquid. Ideally, a liquid placed at a vacuum space would be at its melting point on zero kelvins (absolute zero). Higher the external pressure higher would be the melting point. This is the simple theory behind pressure cookers. A pressure cooker is a device, where the vapor from the heated water is trapped inside the container. The high amount of vapor inside the container makes external pressure on the liquid higher. This high pressure results a higher boiling point. This method is very useful especially on higher altitudes. Since the atmospheric pressure is lower on higher altitudes, water will boil between 80 0C - 90 0C. This will cause undercooked meals. A liquid boils when it exceeds its saturation temperature at the corresponding saturation pressure. Saturation temperature is defined as the temperature corresponding to the highest thermal energy the liquid can hold without changing its state to vapor at the given pressure. The saturation temperature is also equivalent to the boiling point of the liquid. Boiling occurs when the thermal energy of the liquid is enough to break the intermolecular bonds. The normal boiling point is defined as the saturation temperature at atmospheric pressure. The boiling point varies only between the triple point and the critical point of the liquid.
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
flash point
It is the lowest temperature at which a flammable liquid can receive an ignition source and be ignitable. However, once the ignition source is removed, the flammable nature may cease and the flame stop. At temperatures slightly higher, it is when an ignition source is introduced and the ignition source is removed that the flammable liquid continues to burn regardless of the ignition source. The lowest temperature at which a flammable liquid (e.g. gasoline) becomes capable of catching fire in the air. The correct term applied to non-liquids is the autoignition temperature or kindling point.
At room temperature carbon monoxide is a gas. It boils at around minus 191 deg C. By definition flash point is the lowest temperature a liquid material can vaporize to form an ignitable mixture in air. So probably the answer is the boiling point.
Flash Point
This is not the same temperature as the flash point (as read elsewhere on this web site). Flash point of gasoline is negative 45 degrees Fahrenheit, where vapors form fast enough to not be diluted by the air so that the fuel to air ratio is high enough that an alternate source of very high heat (like a spark) can ignite the vapors momentarily, thus removing the vapors from the considered area, and the fire extinguishes. Thus, a flash is seen, hence the term flash point. The fire point is the temperatue where vapors form fast enough to sustain a combustible fuel/air mixture. Ignition point is the temperature of the aforementioned alternate source of high heat, such as a spark, that ignites the a mixture of air and fuel or oxidizer and fuel. I've read elsewhere the ignition point of gasoline and oxygen is 280 degrees Celcius (536 degrees Fahrenheit), and I came here looking for confirmation.
Yes.
The Dew Point.
The temperature in which air is saturated and condensation can occur is the "dew point." It has no specific temperature but it occurs when the air is saturated. The air is saturated when it has a relative humidity of 100 percent, or if i cools down to its dew point.
