What energy is released when petrol burns?
it spreads then stinks lol
How is energy stored in natural gases and how is that energy released?
Natural gas is mostly methane, CH4, which is a hydrocarbon. When it burns with oxygen it releases thermal energy.
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.
What are the types of energies released when a candle burns?
Energy in the form of heat and light is released.
What is the different between cellular respiration and getting energy from a log by burning it?
When a log is burning, it burns energy quickly; and when cellular respiration happens, it burns energy gradually.
What form of energy is produced when you use the candle?
When you light a candle, it burns the wax. That is chemical energy. The thermal energy is produced as the lighted wick continue to burn the wax. It also gives out light as it burns.
Why does a candle burns giving a flame?
We see the light given off as the candle wax burns in the air. Burning is a chemical reaction. When the wax burns, the energy held in the molecular bonds is released as they re-arrange themselves with oxygen, making molecules that are more tightly bound (like falling from some height to lower, that makes kinetic energy). The energy is released as heat and light and in the flame, you see the light and feel the heat.
What form of energy is being used as a candle burns?
The chemical energy stored in the candle wax.
What is the energy conversion of a candle?
As a candle burns, it converts the chemical energy in the wax to heat and light energy.
What energy of coal is released as it burns?
chemical energy into heat energy
What burns on a candle the wick or the wax?
the wick Burns but it produces heat that melts the wax
When coal burns what forms of energy are released?
light and heat energy
What are the products when wax burns?
the product is when parafin wax combines with oxygen.
How is radiation made?
Radiation can come from many sources but all sources that produce radiation do so because of an abundance of energy that they possess. If you want to produce radiation light a candle. The only energy you will need to do this is a lighted match. When you light the candle wick it burns wax from the candle. This wax is stored energy that you have released as radiation in the form of light. I hope this answer is not too trite. gravity guru.
What physical and chemical changes occur when a wax candle burn?
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
How can wax become harmful when melt?
Melted wax can cause burns on the skin.
Where does a lighted candle get its energy to give off light and heat?
The lighted candle burns wax for fuel. The heat from the flame melts the nearby wax, and it is drawn to the flame through the wick. The wick is slowly consumed by the flame, but the wax is the main fuel.
