Do any of you think that spontaneous combustion is possible?
If a reaction brings about an increase of entropy (increase in randomness) and also exodermic, then a reaction is spontaneous. Right?
Yes, I think spontaneous combustion is possible. It happens.
Yes, if delta H is negative and delta S is positive, then delta G is negative for all temperatures and the reaction is spontaneous at all temperatures.
How about spontaneous human
combustion...some of the
theories seem far fetched but
how can you explain some of
the strange accounts of this
happening to people?
I don't know exactly what you are suggesting. If you are suggesting that somehow humans suddenly erupt into smoke and flame due to spontaneous combustion:
a)no, I haven't heard of any such thing.
b)I don't believe it is possible without the aid of kerosene/gasoline and a match or some such reaction, and that isn't the definition of spontaneous combustion.
c)I am unaware of explanations, far-fetched or otherwise, or of any strange accounts.
Spontaneous human combustion refers to the phenomenon where a human body suddenly catches fire without any external ignition source. It has been a subject of debate and speculation for many years. Despite various theories and stories surrounding it, there is currently no scientific evidence to support the existence of spontaneous human combustion as a genuine phenomenon.
Most scientific explanations for cases that were initially attributed to spontaneous combustion involve an external ignition source, such as a dropped cigarette or an unattended heating device, which can lead to the ignition of flammable substances on or near the body. In some cases, the burning of the body's fatty tissues can produce a sustained fire, which may give the appearance of spontaneous combustion.
To better understand the strange accounts of spontaneous human combustion, it is important to critically evaluate the available evidence and consider alternative explanations. Investigating the scene, analyzing the burn patterns, and gathering information about the individual's surrounding environment are crucial steps in determining the true cause of such incidents.
Always remember that extraordinary claims require extraordinary evidence. It is good practice to approach accounts of spontaneous human combustion with skepticism and rely on scientific analysis and investigation to find the most plausible explanation.
