Combustion of candle wax, heat loss within a system, and physical/chemical changes that occur are a result of energy Transformers.
Lighting a match and igniting a candle. Using a lighter to start a campfire. Burning wood in a fireplace for warmth.
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.
Materials burn due to a chemical reaction with oxygen, releasing heat and light in the process. When something starts burning, it undergoes combustion, breaking down into simpler compounds and releasing energy in the form of heat and light. The purpose of burning materials can vary, such as for generating heat, producing light, or as a means of disposing waste.
every thing come from the sun the plants get there energy from the sun so that's where the source
The sun is the source of all energy except geothermal.

Energy is never "used" it is always converted to another form of energy.Therefore, there must be different forms of energy which are:1. Chemical2. Electrical3. Elastic4. Nuclear5. Thermal6. Gravitational7. Kinetic8. Light(9. Sound)When a candle burns the chemical energy is converted into thermal or "heat" energy.
A candle burning is exothermic because it releases heat and light energy as it undergoes combustion. The chemical reaction between the wax and the oxygen in the air releases more energy than it takes to start the reaction, resulting in a net release of energy.
The burning candle releases energy in the form of heat and light, which is then absorbed by the air molecules. These air molecules gain kinetic energy and start moving faster, causing them to push the pinwheel and make it rotate. So, the energy transformation path is: chemical energy (candle) → heat and light energy → kinetic energy (air molecules) → mechanical energy (pinwheel).

Start first candle from one side burning and second candle from two side burning. So second candle will take 30 min to finish. When second candle finished make first candle also to burn from both side. So now remaining of first candle will take more 15 min to finished. So total life of burning of fist candle is 45 mins.
While the body is in a fasting mood, the body will move to a ketosis state and start burning fats as a source of energy to the body.
partial combustion takes place here and wax vapour start burning with a yellowwish flame . this region of candle flame is moderately hot. so it is called as the luminous zone
you run into a state called Ketosis. That is your body senses that you don't provide instant energy source and you provide only protein and fats. So it will start using protein to build and safeguard the muscle and will start burning fat as main fuel source.
When a candle smell like comes from any where of your vehicle it migth be a wire getting too hot, the revestiment of wires are made of plastic which when start burning but not enough to flame it the smell will be like a candle.
Not spontaneously. But, it could easily burn if it is near a heat source, like a candle or a heater.
