Why materials burn and what happen when something start burning and what is the purpose of burning materials?
materials burn because of a chemical reaction that occured within the material. as for the purpose there can be many... you can burn wood for warmth or a candle because it smells good
Which is the best description of activation energy?
The amount of energy needed to start a chemical reaction. Source: Biology class
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.
What does the energy pyramid first level start with?
every thing come from the sun the plants get there energy from the sun so that's where the source
What is the energy used by all living things starts with what?
The sun is the source of all energy except geothermal.
What energy source is used to start the burning of a candle?
matchsticks
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 you have 2 candles Every candle lights for 60 minutes If you have to find the way to measure 45 minutes?
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.
How does someone that only eats once a day lose weight?
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.
What are the essential elements in order that combustion take place?
there should b presence of oxygen....
What happens to protein and fat if the diet is deficient in carbohydrates?
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.
Why is middle zone of the candle called luminous zone?
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
How can you make the chemical energy in the matchstick useful?
Strike the match and start it burning then it can be used
What are the nonrenewable fuels start with the sun as there primary source of energy?
all nonrenewable fuels can be traced back to the sun as a primary energy source
What does it mean if your car is smelling like candles?
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.
Can a dried house plant combust and start a fire?
Not spontaneously. But, it could easily burn if it is near a heat source, like a candle or a heater.
