Can we have a fire without flames?
Fire may burn either with or without flames.
A flame always indicates that heat has forced gas from a burning substance.
The flames come from the combination of this gas with oxygen in the air..
Is plasma hotter than fire?
Plasma is different: it’s gas with its atoms’ electrons stripped off and free to flow. … In other words, it requires temperatures far higher than fire to produce the “hard” ultraviolet light and the electrical effects seen in plasmas. Your flame can’t just be white hot or blue-hot, it must be UV-hot.
Is fire a plasma or gas?
Learn more physics! Fire is an oxidizing chemical reaction that releases heat and light. The actual flames that you see moving and glowing when something is burning are simply gas that is still reacting and giving off light. Plasmas are gases in which a good fraction of the molecules are ionized.
What is the difference between fire and flame?
Flame is a stream of hot, burning gas from something on fire: Fire (material that is in) the state of burning that produces flames that send out heat and light, and might produce smoke: It seems that the “fire” refers to the state while “flame” refers to the result of this state.
Is the Sun Fire or plasma?
It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. The first state is a solid and it is the coldest state of matter. As we heat up a solid it becomes liquid.
What is flame made of?
Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire’s intensity will be different.
Is fire a liquid?
The flames are obviously not solid, nor are they liquid. Mingling with the air, they’re more like a gas, but more visible–and more fleeting. And on a scientific level, fire differs from gas because gases can exist in the same state indefinitely while fires always burn out eventually.
What is a fire that starts without a flame called?
Autoignition. Initiation of combustion by heat but without a spark or flame. Autoignition Temperature.
Why is fire not plasma?
The bottom line is that a flame only becomes a plasma if it gets hot enough. Flames at lower temperatures do not contain enough ionization to become a plasma. On the other hand, a higher-temperature flame does indeed contain enough freed electrons and ions to act as a plasma.
What is the 5 states of matter?
The classical states of matter are usually summarized as: solid, liquid, gas, and plasma.
What substances burn without flames?
Liquefied petroleum gas (LPG), also referred to as simply propane or butane are flammable mixtures of hydrocarbon gases, used as fuel in heating and cooking equipment and produce a blue flame. Camphor gives a flame, which is widely used in worship. Charcoal, does not vaporise and so, does not produce a flame.
What state of matter is flame?
gasWhile there is a small amount of ionization going on in an ordinary fire, most of the matter in the flame is a gas. Thus, the safest answer for “What is the state of matter of fire?” is to say it’s a gas. Or, you can say it’s mostly gas, with a smaller amount of plasma.
What color fire is the hottest?
The hottest fires are from oxyacetylene torches (about 3000 degrees Centigrade) that combine oxygen and gas to create pinpoint blue flames. Color also tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 °C).
What is triangle of fire?
Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
Why is fire not a matter?
Matter is anything that has mass and occupies space. The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. The light produced by the flame is energy, not matter. The heat produced is also energy, not matter.
