What else can I help you with?
Is burning of candel is spontaneous process?
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.
Can a candle burn on the moon?
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.
Is candle burning a spontaneous or non spontaneous reaction?
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.
What are differences between rapid and spontaneous combustion?
The spontaneous combustion flows very slowly and occur by self heating.
What does candle need from air to burn?
A candle requires oxygen (O2) to continue its combustion reaction and produce CO2 and H2O.
If a plant and a burning candle are placed under a bell jar will the candle burn?
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.
Why is candle flame yellow?
candles burn with a yellow flame because its an incomplete combustion
Does air effects length of time for a candle to burn?
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
Why does a candle not burn on the surface of the moon?
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.
Why the candle could not burn when gas left in the jar?
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.
Why candle burns longer in oxygen?
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.

What causes things to burn?
This could be a few different things ... 1. Fire 2. Heat 3. Spontaneous combustion
How do you release spontaneous combustion?
There is no way to release spontaneous human combustion voluntarily or involantarily
What is the duration of Spontaneous Combustion film?
The duration of Spontaneous Combustion - film - is 1.62 hours.
Does a candle need oxygen to burn?
Yes, a candle needs oxygen to burn. When the wick is lit, it melts the wax, which vaporizes and combusts, reacting with oxygen in the air to produce heat and light. This process is known as combustion.
