Burning a candle is not spontaneous combustion. That is when something ignites with no outside heat source. If a candle burst into flame with no match or lighter, THAT would be spontaneous combustion.
Yes, candle burning is a spontaneous process. A spontaneous process is defined as: once it is allowed to start, the process will proceed to the finish without any external intervention. You lit the candle, it was allowed to burn and it would keep going without any help. The Gibbs free energy change for this process is negative. On the other hand, the decomposition of CaCO3(s) is NOT a spontaneous process. You have to keep heating the reaction vessel in order to decompose all CaCO3. Outside intervention is needed for this process to finish.
No, a candle can't burn on the moon if it's not in some kind of atmosphere containing oxygen. The moon really doesn't have any atmosphere, and that means no oxygen to support combustion of any kind.
The spontaneous combustion flows very slowly and occur by self heating.
Candle burning is a spontaneous reaction. It is an exothermic reaction that occurs naturally and releases heat and light energy as the wax is being oxidized in the presence of oxygen from the air.
Candles need oxygen from the air to burn. When the candle is lit, the heat from the flame vaporizes the wax, which reacts with oxygen to produce heat, light, carbon dioxide, and water vapor.
No, the candle will not burn because the flame will consume the oxygen inside the bell jar, creating a vacuum and extinguishing the flame. Oxygen is necessary for combustion to occur, and without it, the candle cannot burn.
candles burn with a yellow flame because its an incomplete combustion
for combustion to take place there has to be heat, oxygen and a fuel. On the moon there is a fuel (wick of the candle) and heat(your fire source) but no oxygen as there is no atmosphere which makes combustion (burning) impossible.
yes.you need more air,as the candle will burn for longer in a bigger volume of air because the air contains oxygen which is needed for combustion
When gas is left in the jar, it displaces the oxygen needed for the candle to burn. Oxygen is required for combustion to occur. Without enough oxygen present, the candle will not be able to sustain the flame and will extinguish.
There is no way to release spontaneous human combustion voluntarily or involantarily
The duration of Spontaneous Combustion - film - is 1.62 hours.
Candles burn longer in oxygen because oxygen efficiently supports the combustion process. The heat produced by the flame breaks down the candle wax, releasing fuel molecules which combine with oxygen to continue burning. In contrast, if the candle is in a limited oxygen environment, incomplete combustion occurs and the candle burns at a faster rate.
This could be a few different things ... 1. Fire 2. Heat 3. Spontaneous combustion
Yes, sponge iron is susceptible to spontaneous combustion due to its high reactivity with oxygen. Proper storage and handling procedures are necessary to prevent this risk of spontaneous combustion.
