سوال: شعله ی کدام عنصر یا ماده ی شیمیائی حرارت کمتری داره ؟

سلام
کدام عنصر یا ماده ی شیمیائی وقتی میسوزه حرارت کمتری تولید میکنه ؟
این حرارت چند درجه هست ؟
آیا میشه ماده ای بسوزه و شعله تولید کنه اما حرارتش زیر 40 یا 45 درجه باشه ؟
بیشترین حرارت مربوط به شعله ی کدوم ماده هست ؟
با تشکر

yes. It is carbon disulphide CS2
easier and more accessible is mixing ethanol with water that when ethanol burns, water evaporation takes its heat and therefore it does not create too much heat but still continues burning if a good water/ethanol ratio is used.
how many percent water and ethanol? I don;t remember. you can search on the internet to hopefully find the anwer

I should add that even in case CS2, you need to add CCl4 that is a liquid that does not burn, to reduce the heat. while CS2 is burning, CCl4 evaporates and takes the heat off
