Which is to burn longer a tallow candle or a wax candle?
If you freeze the candle, before using it, it will burn for a longer period of time. ANSWER Beeswax burns very quickly.
What led humans to burn fossil fuels?
They discovered coal could burn longer than wood. They used it to drive steam engines which could power vehicles and factories. At that time nobody knew about carbon dioxide emissions and how they cause global warming.
Which candles would burn longer cake with 8 candles or cake with 7 candles?
As long as they were all lit at the same time, they would burn for the same amount of time (regardless of the number of candles).
Do white candles burn faster than colored candles project materials?
No. you could time them.
Why is daylight on Venus longer then daylight on Earth?
Because it takes a longer time to rotate than earth does
What is the difference between 91 octane and 95 octane?
91 octane petrol will ignite at a lower temperature and burn faster, which can cause knocking in an auto engine. Lead compounds were added at one time to raise the octane rating, but recently engines have been redesigned to work on low (<98) octane petrol (or gas in the US colonies)
Does the thickness of a candle affect the burn time of a candle?
Yes, thicker candles have more wax to burn and therefor take longer to burn out.
Writing a topic page on do colored candles burn faster than white candles?
white candles burn faster because colored candles have more chemicals which take a longer time to burn,although it also depends on the wick of the candle if it is cheap it wont burn if its a good quality wick it will burn. =) my science fair project...
Can you burn a candle inside a jar?
For a short time with the lid on or for much longer with the lid off.
Why does kerosene oil catch fire faster than wood?
This is because the specific heat capacity of the wood is more than the kerosene oil. So, the wood takes time to burn but burns for longer period than the kerosene oil.
What happens when pulse on time increase in edm process?
Basic what happens. Is with longer on time duration (pulse) you get higher burn rate. But a correct balance of on and off times is how you keep from wearing the electrode more than the part.

Is there a difference from packing or not packing cigarettes?
Packing cigarettes supposedly compacts them so that it will take longer for the tobacco to burn, providing for a longer smoking time.
Will it hurt the motorcycle if you mix 87 and 93 octane gas?
The question is, what octane does the motorcycle require?If it needs 92 or 93, and you mix 87 and 93, you are probably not meeting the requirement. That could damage the engine due to pinging.Lower Octane means a more powerful and hotter explosion. Octane ratings vary, usually due to stroke time or compression ratios which increase the temperature of the air in the cylinder and pre-ignites the gas mixture (pinging), sometimes it has to do with aluminum in the head. If your bike manual asks for 92, put in 92.Lower Octane = More powerful explosion, very short burn time, hotter burnHigh Octane = Weaker and slower explosion, colder burn.Putting higher octane fuel in a lower octane engine usually results in poor perfromance because the power stroke has finished while the fuel is still burning.
Which candles would burn longer cake with 8 candles or cake with 7 candles?
As long as they were all lit at the same time, they would burn for the same amount of time (regardless of the number of candles).
Does a Yamaha fzr 600 take 93 octane gas premium or just regular 87 which is recommended?
Answervery very wrong>if i were you i'd use premium it's better for your bike< Listen regular premium and mid grade are all different octane ratings octane refers to the volatility of the fuel to combustion. Ok the simple version low octane burns easier premium is harder to burn. The Fzr calls for regular which is 87 octane! that's regular now if you put premium which is harder to burn then your going backwards. Using premium since its harder to burn leave carbon deposits which are not good at all for the motor leading to the compression rising after time makeing the tolerances closer making the motor a whole lot more likely to fail. I build hi performance motors and attended mmi (motorcycle mechanics institute) Plus the crappy additives in premium will do more harm then good the moral to the story just follow the bikes instructions and you will have a good runing bike for years.This is incorrect regarding Octane rating. Gasoline is a mixture of several petroleum distillates of which octane is one. The higher the octane the slower the mixture "burns". Engines are designed to take into account the speed at which the air-fuel mizture burns. The technical keyword here is "flame front velocity". Another keyword is pre-detonation.The engine timing is such that the correct octane rating assures that fuel is burned at an optimal rate during the power stroke. Too low a octane rating results in the familiar "pinging" heard in automobile engines which means the fuel burned faster than the optimal speed for the power stroke.This is why you would retard the ignition if you are burning too low an octane rated fuel.Most likely no damage would occur from being slighlty off from the suggested octane rating. However using too low an octane fuel over a long period of time could lead to excessive wear to engine internals.But as suggested the safe route is use fuel with the octane rating suggested by the manual.The first guy was right second one wrong. Lower octane rating means more volatile more eager to burn, were higher octane harder to burn.----------------------------------------------------------------No, the second guy is right, the first is dead wrong - as is the third!The confusion surrounding octane is unbelievable. "Octane" is a measure of the fuel's reaction kinetics (higher octane, slower burn). Volatility plays NO ROLE in octane rating whatsoever. Gasoline is made up of hundred of compounds centered around chains that are 8 (octane) carbons long. If these chains are straight (n-Octane) the molecule reacts very quickly and lead to detonation in the cylinders. Pure n-Octance has an octane rating of about 37. If the chains are branched (iso), they react slower because some of the bonds are hidden and the flame front is subsonic. Detonation occurs when the flame front is supersonic, resulting in shock waves much like those experienced on airplane during sonic booms.Burning an unnecessarily high octane will often result in less power and isn't BETTER for your motorcycle. Some higher octane gasoline containa better detergent package but in general most high octane gasolines are higher because ethanol is added in greater concentration. Ethanol has a very high octane rating (burns very slowly) and so adding a more of it into the fuel will raise the effective octane of that mixture.Cars can adapt to slower buring fuels because they "sense" when a fuel isn't knocking (detonating) with a knock sensor and constantly "test" the fuel and advance the timing a bit to take give the flame front time to develop.These types of sophisticated ignition systems don't exist on most bikes.So the answer is that you burn the lowest octane that DOESN'T detonate. If your bike runs well on 87 octane, that's what you use. Using a 92 octane will only rob you of power and result in lower efficiency.Sam,Chemical Engineer
