Scientists have been finding new things about new creatures daily. Dragons are one of those many creature. They are very large with claws, fangs, and enormous wings. They also happen to breathe fire. Scientists have been pinning over questions about them for many years. The question that has been most researched is: How could dragons have breathed fire? Now, finally, they found an answer. Actually they found many, but the answer magic won’t due, scientists have found scientific ways in chemistry and other sciences. So let’s burn our way through the three theories about how dragons can breathe fire and ignite curiosities even further.
Fire needs three key things to ignite: heat, fuel, and an oxidizing agent (usually oxygen). Supposing dragons breathe like mammals, the oxygen that dragons draw into their lungs isn’t completely depleted when they exhale . For healthy humans inhaling it’s about 20.9%, and exhaling it’s about 15.3%. Not a huge difference, but this is a dragon and they would have to have larger lungs so a larger lung capacity, and a larger amount of oxygen left in their lungs after exhaling. The amount of oxygen they would still have in their body after they exhaled wouldn’t be too much, but it would be just enough to coax a small flame out of the dragon’s body (not nearly large enough to burn the inside of the dragon’s mouth). When it’s out, the oxygen in the air will keep it alive. As you can see in the picture to the left, the dragon is emitting fire outside the mouth. There is only a little flame as inside of it so there is no reason that the dragon would burn the inside of its mouth, and it also proves that they use the oxygen in the air.
Next in the line of fire is fuel. The fuel that scientist think dragons make ...

(blackdrago.com) “Dragon images have been found on the Ishtar Gate of Babylon, on scrolls from China, in Egyptian hieroglyphs and Ethiopian sketches, on the prows of Viking ships, in bas relief on Aztec temples, on cliffs above the Mississippi River and even on bones carved by Inuits in climates where no reptile could live.” (McNeil) Stories of dragons can be found all through history. Over five thousand years ago, ancient Sumerian cultures had dragon legends in their religions. Modernly, few still believe dragons exist, they can still be found in our movies, books and video
Dragons lie in the realm of fantasy; legendary creatures who are deeply rooted in magic and have captivated audiences for centuries. The depiction
When the dragon awakes after three hundred years of sleep, he discovers that his cup has been stolen. The dragon, also known as the worm, fills with anger and rage. Even though he is so angry, he does like the idea of battle: “Yet he took joy in the thought of war, in the work of fighting” (Donaldson 40). The dragon cannot wait to ravage the land of the people where one man has stolen from him: “The hoard-guard waited restless until evening came; then the barrow-keeper was in rage: he would requite that precious drinking cup with vengeful fire” (Donaldson 40). The dragon destroys the land and kills everyone around. The dragon even destroys Beowulf’s home.
By using the fiery imagery, the dragons automatically become evil and threatening to the heroes of the
Dragons are very popular mythical beings because they are capable of flying, swimming, and walking on land. This makes a Dragons attack much easier because he can exploit the weaknesses of his victims by using earth’s natural elements earth, air, fire, and water. Dragons have sharp teeth and a tongue shaped like an arrow. These creatures can breathe fire, but some cultures believed they spit ice or another venomous substance. All a dragons power is in its long, scaly tail.

The king, wanting to be fair, put the matter up to vote, and the people decided the dragon needed to be killed. Thus, the king and men rode out into the woods, bearing crossbows and lances, to slay the dragon.
The debate of whether dinosaurs were cold blooded or warm blooded has been ongoing since the beginning of the century. At the turn of the century scientists believed that dinosaurs had long limbs and were fairly slim, supporting the idea of a cold blooded reptile. Recently, however, the bone structure, number or predators to prey, and limb position have suggested a warm blooded species. In addition, the recent discovery of a fossilized dinosaur heart has supported the idea that dinosaurs were a warm blooded species. In this essay, I am going to give supporting evidence of dinosaurs being both warm and cold blooded. I will provide background information on the dinosaur that was discovered and what information it provides scientists.
Although fire is linked to human life, as it is essential for survival, not only its use for food, security and warmth, particularly in the extreme cold weather
Throughout the old world, people had feared creatures with the body of a large lizard, snake-like eyes, large wings, and that can emit fire from their mouth. They was thought to be the embodiment of evil, greed, lust, violence, and the dark side of humanity. These mythical creatures are called dragons, but the dragon have a different reputation in the Eastern world. In China it was highly respected in the kingdom, a fairly common motif in eastern art for its heavenly related background.
Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health.
When gasoline burns in the engine of a car, an equal amount of work and heat appears as the energy is released. The heat from the engine warms its surroundings, the car parts, the air, and the passenger area. The heat energy is converted into the electrical energy of the radio, chemical energy of the battery, and radiant energy of the lights. The change in the sum of all of the energies formed from the burnt gasoline is equal to the “.change in energy between the reactants and products.” Biological processes, like photosynthesis, also follow energy conservation.
“Dragons. Four fully grown, enormous, vicious-looking dragons were rearing on their hind legs inside an enclosure fenced with thick planks of wood, roaring and snorting- torrents of fire were shooting into the dark sky from their open, fanged mouths, fifty feet above the ground on their outstretched necks.” (p286)
The next era is the end of the 17th century- mid 19th century also known as “traditional chemistry”. In the 1700’s, Johann J. Beecher discovered a substance called phlogiston. When substances burn, phlogiston is supposedly added from the air to flame the object that’s burning. Charles Coulcomb the ...

On top of the effects on the earth as well as humans, there is only one thing we all can do and that is listen to our old pal Smokey the Bear when he says, “only you can prevent wildfire.”
