What supplies the activation energy to light the candle?
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.
If a candle is in a box with two openings and the candle is burning under the left opening why does the air come through the right opening instead of the left opening?
The air comes through the right opening instead of the left opening because hot air from the candle leaves via the left opening.
How does a mandle candle work?
A new generation of candles! These candles light up from the inside. The patented micro-electronic technology allows the candle to emit a multitude of constantly changing colours throughout the interior of the candle. The power source is an environmentally friendly Lithium battery with a life span of about 20 hours. Come nicely gift boxed with instruction leaflet. Also known as 'Mandle Candles' or 'LED Candles' there are 8 types to choose from. from the mandle candle website. A new generation of candles! These candles light up from the inside.

Why is a burning unattending candle unsafe?
An unattended burning candle can lead to fires if left near flammable materials or if the flame spreads. It could also cause injuries if pets or children come too close to the flame. Additionally, the candle could burn out completely and leave a hot ember or wax puddle unattended.
Where does the heat energy and light energy of a candle come from?
The heat energy and light energy of a candle come from the chemical reaction of the candle wax (hydrocarbons) combining with oxygen from the air. This reaction releases energy in the form of heat and light. The heat energy is produced when the chemical bonds are broken and reformed, while the light energy is generated by the incandescence of the soot particles in the flame.
Where did Burning candle at both ends originate?

How does voltage come from a candle?
Voltage does not come from a candle. A candle produces light and heat through a chemical reaction when the candle wax is burned. Voltage is typically generated by batteries or power sources that convert energy from various sources into electrical potential.
Does energy come from burning fossil fuels?
Yes, certainly it does
What is the chemical potential energy of a burning tea light candle -mini candles?
It is the thermal energy released by the candle's material when it burns. Wikipedia gives a figure of 40 watts for a burning candle, so if it burns for 1 hour that is 40 watthours, or 144,000 wattseconds = 144,000 Joules. The thermal energy released by burning paraffin wax is 42,000 joules/gram, so that energy release represents about 3.5 grams of wax. My mini T-light candles weigh 20 grams and the packet says will burn for 9 hours, so that would be 2.25 grams per hour. This is in the right street, but the flame from these mini candles must be less than 40 watts, more like 25 watts. Of course in reality you can never burn every scrap of wax, there is always some wastage in the form of a stub you get left with, and some wax may melt and run away without getting burned.
Where does water vapour from a candle come from?
The heat from a candle is stored in the chemical bonds of the oxygen and the candle wax. When you use a match to light the candle, you are activating the chemical reaction between the oxygen and the wax, which releases the energy stored in the bonds of the wax and oxygen. The products of the reaction, carbon dixode and water, require less energy for their bonds. So, all the extra energy that was stored in the wax and the oxygen is released to the air around the candle (the extra air that's not being used to react with the wax). Remember, if you put a jar over a candle, it will go out because it runs out of oxygen to react with.
If a candle is in a box with two openings and the candle is burning under the left opening why does the air come through the right opening instead of the left opening?
The air comes through the right opening instead of the left opening because hot air from the candle leaves via the left opening.
Biomass involves burning organic materials to release chemical energy What are the steps in the Carbon Cycle that describes this process?
biomass burning is perceived as being a sensible form of energy generation. ... So the potential is there for a substantial fraction of our energy budget to come from biomass burning.
Does fire need energy?
Yes, fire does require energy to ignite and continue burning. This energy can come from sources such as heat, light, or a chemical reaction. Once the fire is burning, it releases energy in the form of heat and light through a process called combustion.
How does electricity come from candle?
I can think of three ways whereby a candle could produce electricity: 1). Heat water with the flame. When the water boils, use the steam to spin a turbine mounted to an electrical generator. 2). Place the flame close by a photovoltaic cell, which can convert a part of the candle's heat and light to electrical energy. 3). Place a pinwheel behind the candle flame, attached to an electrical generator, and wait for someone to come along and blow out the flame.
