Just a guess- but most have a sensor known as a thermocouple. This detects the heat of the flame of the pilot light, and keeps gas from flowing if the pilot light is not lit. check that your pilot light (a very small flame) is burning, and that the flame heats a small metal tube- about as big as a wooden match. If pilot is out, get it lit, and let burn for 5 minutes, and try lighting fireplace. If it still will not stay lit, the thermocouple may need replacement- they DO wear out. Check with your local gas appliance repair service. While they are fixing it, have them show you correct lighting process.
When copper burns, it undergoes a chemical reaction with oxygen in the air to form copper oxide. This reaction releases heat and produces a colorful flame that is typically green or blue. Copper oxide residue is left behind after the burning process.
To create a safety flame on a Bunsen burner, adjust the air hole to allow more air to mix with the gas. This will produce a hotter, lighter blue flame rather than a yellow, sooty flame. Adjust the gas flow until the flame burns steadily without flickering or making noise.
Gas will stay in a cup. If the gas is denser then air, it will settle into the cup and stay there in much the same way that a liquid will. If the gas is close to the same density as the air, or lighter, it will float away and mix with the air.
Inside the balloon with no water at all, the intense heat from the hot fire will melt the surface of the balloon. The pressure inside the balloon is so big that the balloon deflate and POP! With water, the water conducts the fire away from the balloon so the suface may not reach high tempertures. The balloon is remained inflated.
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...
The flame detector on the pilot assembly is probably defective. If you do not know how to fix this, call you gas supplier and have it repaired.
Not an expert, but a homeowner. MOST gas fireplaces (and other appliances) have a flame sensor- frequently in the form of a thermocouple. Intended to prevent gas from flowing when there is no flame present. If the thermocouple is bad, it will shut off the gas flow even when a flame IS present. It may look like a small rod that is in the flame of the pilot light. I would REALLY hand this of to a professional gas repairman. The cost of having this done right is FAR less than the cost of doing it wrong.
Stay in what? More information needed. It's none of your business why my penis wont stay in
The Medeival peasants normally cooked their foods on a consistant burning flame of fire. For the more wealthy they had good big burning fires so their food would be eatern in a different manner to the peasants. I mean would a barron wont their food cooked peasant style.
When burning magnesium the light shines much brighter... so much to the point where it can blind your eyes if you look directly at it while burning... on the other hand methane can be observed while being lit and it wont mess up your sight in other words it is NOT nearly as bright!
dd
CO2 is th gas used, if you starve a fire of oxygen then it wont have anything to burn
What colour the flame is has totally got to do with how much oxygen is allowed into the Bunsen, the flame can be anywhere between a bight orange to blue, all the way to being almost unnoticeable. This is what make them dangerous if unattended as you wont know there burning until you are. Low air easily visible flame, High air flow, and it becomes very difficult to see.
I will stay comb
it wont stay in your system it's legal so therefore wont be on your system so it's completely safe
