The hottest part of a flame is the point ofmaximum combustion, which is the blue portion of a flame (if the flame burns that hot). However, most students performingscience experimentsare told to use the top of the flame. Why? Because heat rises, so the top of the flame's cone is a...
aWalsn Flame Detection System is the essential equipment for the FSSS of coal-fired, gas-fired and oil-fired boilers. Based on the physical property of flame, the detector detects the combustion condition in real time. Once the flame is off or the combustion conditon is abnormal, the detecto...
heard the legend of the blue flame, or at least that you can light a fart on fire if you do it right. Many pants have caught on fire in an attempt to prove this, so you really shouldn't try this at home (especially when you've been drinking). That being said,it is possible to...

Which alkali metal gives blue in flame test? Most of the alkali metals glow with a characteristic color when placed in a flame; lithium is bright red, sodium gives off an intense yellow, potassium is violet, rubidium is a dark red, andcesiumgives off blue light. These flame tests are use...
But why is it that the leaves of some trees don't turn red? SEE ALSO: The colour blue is elusive in nature. Here's why The answer is perhaps better explored by asking why some do. And, interestingly, there’s still a lack of consensus around the an...
Question: Why does displacing copper using zinc produce a black precipitate? Precipitate: Precipitates are the solid insoluble products produced in certain reactions which are taking place in a solution. Such reactions are generally termed precipitation reactions. Sodium chloride is an example of a prec...
Why is it so important that volumetric glassware be clean before measuring samples of liquids? Why do the chemicals have to be heated in the flame before the colored light is emitted? Why are some LDPE used in packaging films rather than HDPE? Why does the sky turn orange...
