Because of the law of conversation of mass
What else can I help you with?
Explain why the mass of a candle does not disappear while burning?
Because of the law of conversation of mass
How does the law of conservation of mass to a burning candle?
The mass of the initial candle is identical with the sum of masses of released gases from burning and the residues remained.
If the gases released by a burning candle could be contained and measured would you see that their mass is the same as the candle's was before it was lit and what law does this example describe?
This experiment is a verification of the law of the conservation of matter. And yes, the mass of all the combustion products would be equal to the mass of the candle and the oxygen it consumed while burning.
How could you check that mass of the candle change during burning?
Put the candle on a technical balance.
Is a burning candle an example of an opened system or a closed system?
A burning candle is an example of an open system because it exchanges both energy (in the form of heat and light) and mass (as the candle wax burns) with its surroundings.
Is the heat from a burning candle matter?
No, the heat from a burning candle is not matter; it is a form of energy. Matter consists of substances that have mass and occupy space, while heat is the energy transferred between objects due to a temperature difference. The heat generated by the candle results from the combustion of the wick and wax, which produces both thermal energy and light.
How does burning candle affect mass differently than melting a candle?
When a candle burns, it undergoes a chemical reaction called combustion, where the wax reacts with oxygen to produce carbon dioxide and water vapor. During this process, the candle's mass decreases as some of the wax is converted into gases. On the other hand, when a candle melts, it transitions from solid to liquid state, but its mass remains unchanged as no chemical reaction occurs.
When a candle is burning does that violate the laws of conservation of mass and energy?
No. -- Mass leaves the candle in the form of hot gases and soot, and there's always some of it left in the puddle of melted wax under the candle. -- Oxygen combines with the hydrocarbons in the candle material and the fibers in the wick, releasing chemical energy that leaves the candle in the form of heat and light.
A lit candle on a balance losses mass why?
The wax of the candle is made from hydrocarbons - compounds made up of carbon and hydrogen only.When hydrocarbons burn in a plentiful supply of air they all produce the gas carbon dioxide and water vapour, both of which dissipate into the air.So when a candle burns, its wax is slowly being converted into carbon dioxide and water vapour which disappear into the air surrounding the candle, and so its mass appears to decrease.However, if you collected all the carbon dioxide and water vapour given off by the burning candle, and weighed it, you would find that it weighed more than the wax from which it came, because in the process of burning he wax had combined with the oxygen in the air, thus increasing its mass.
Mass does not change during a chemical change how about for a physical change?
Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.
Does the wick effect how fast it burns?
"http://wiki.answers.com/Q/Does_the_wick_effect_how_fast_it_burns" To the best of my knowledge the speed of burning is a function of the size and volatility of the candle material. The wick serves only to keep the candle material melting, vaporizing and burning, it apparently burning at a higher temperature than the candle mass. See:http://www.howstuffworks.com/question267.htm
How can the Law of Conservation of Mass apply to a burning log?
As the solid wax melts and cumbusts, the wax combines with oxygen and turns into a gas, carbon dioxide among other things. The mass of the wax and wick are converted into gases and the mass is conserved.
