why are embers hotter than flames?

Embers can glow very hot, sometimes as hot as the fire which created them. ... This is because embers radiate a more consistent form of heat, as opposed to an open fire, which is constantly changing along with the heat it radiates.

Azula's fire was made blue to denote both her mastery in both firebending and lightning-creation. Azula's fire burns hotter than most due to her lightning-mastery, but will turn orange as it cools. Second in raw power only to the Fire Lord Ozai, she was a force to be reckoned with.

A bonfire is much more massive than a campfire. They're usually built for a huge outdoor event, signaling device, or a celebration. Even though a bonfire is a controlled fire, the size makes the fire more dangerous than a campfire. Bonfires are put together in open areas such as meadows and fields.

Ignition temperature is the lowest temperature at which a combustible substance when heated (as in a bath of molten metal) takes fire in air and continues to burn. Fire point is the lowest temperature where the vapor of a liquid will initiate and sustain a combustion reaction .

Fire is combustion of a gas, the Sun is a ball of nuclear fusion (no actual "burning"). Fire is not very dense (s.g. = . 01 g/cc) vs the sun is very dense, even denser than lead (s.g. = 160x denser than water). Fire is 1000 to 3000 degrees F.

Candle burns with a flame but coal burns with only a glow. This is because only substances that vapourize while burning gives flame. Thus candle burns with a flame because it vapourizes while burning and coal burns with a glow because it does not vapourize while burning.

Flame is calorie burn. Heart is for Heart rate. lighting bolt is active minutes.

Ice reflects blue light, so cold temperatures are associated with blue. Fire emits red light. However, note that the fire is emitting the light rather than just reflecting it: a flame that is hot enough will emit blue light, and is hotter than the red-emitting fire.

Once they start burning, there is no smoke because the hydrocarbons are turned into carbon dioxide and water (both invisible) when they burn. This explains why you see no smoke from a charcoal fire (or a fire that has burned down to embers).

Fire is burning, which is combustion, and combustion is a type of oxidation reaction. Oxidation means combined chemically with oxygen . Oxidation is an exothermic reaction, meaning it gives releases heat energy.

The Sun isn't "made of fire". It's made mostly of hydrogen and helium. Its heat and light come from nuclear fusion, a very different process that doesn't require oxygen. Ordinary fire is a chemical reaction; fusion merges hydrogen nuclei into helium, and produces much more energy.

While a luminous flame burns yellow, a non-luminous flame burns blue; this is because of the difference in available levels of oxygen. Luminous flames have limited access to oxygen, while non-luminous flames have unlimited access to oxygen.

An oxidant flame is the hottest flame. An oxidant flame is the (hottest/coldest) flame. Acetylene burns at a temperature of 5500 degrees Fahrenheit.

William, I looked it up and came up with this referring to coals: These have less moisture content and tend to be denser than a natural log, so they burn hotter and longer. ... While forests can burn for months at a time, there is a coalseam fire in German that has been burning since the 1600s.

While ionisation sensors will usually respond quicker to 'flaming' fires, optical sensors will almost certainly respond quicker to the 'smouldering' type of fires. ... Ionisation is the more sensitive of the two and will provide an earlier alarm to an impending fire condition.

Electric heat is usually a much safer way to cook. There's no flame or combustion, there are no pressurized fuel tanks, and other than the delicious scent of your food cooking, there are no fumes. Most electric BBQs can be easily broken down for cleaning, and they're often non-stick.
