What is spontaneouhuman combustion?

Answer 1

Spontaneous Human Combustion is the theoretical chance of a human body catching fire for no reason, e.g. without any external heat source. Spontaneous combustion of other things does happen, for example in wet hay, this is due to heat produced by bacterial activity in the hay. Finely divided materials are more likely to combust readily than solids as the chemical reaction involved in fire will speed up in finely divided particles. There is no scientific evidence for spontaneous human combustion. One theory is that some bodies may appear to burn on their own when involved in a fire. There is some evidence that the wicking effect as evidenced in candles burning may also happen in human combustion as the quantity of fat in the body may melt in a slowly developing fire in as similar way with the bones acting in the same way as a candle wick. This has been tested in experiments. The appearance of the body may then appear to have burned on its own with no external evidence as the original source of the fire may have been completely destroyed in the fire.
