Ask your question. This is hot enough to melt almost all metals, except maybe some superalloys. It is also used by industry to produce phosphoric acid and other chemicals for use in fertilizers, food additives, and cleaning compounds. Click here to get an answer to your question ️ Phosphorus burns at (a) room temperature (b) 100°C (c) cool temperature (d) any temperature White phosphorus is self-igniting when it interacts with oxygen at a temperature of 86 degrees. The (C) is a liquid at room temperature and neutral to moist litmus paper while the gas (B) is a neutral oxide. White phosphorus particles can burn on the surface of the skin or penetrate deep into the tissues when carried on shrapnel particles. It continues to ignite until it is either consumed or deprived from oxygen. The max is 75 degrees but keep the water at 69 because most goldfish like that temperature. I know that Dicyanoacetylene (carbon subnitride) combusts at a flame temperature of 4990°C. First aid for this type of burn is complicated by the fact that white phosphorus particles ignite upon contact with … From what I've heard, it burns consistently at a temperature of 30 degrees celsius, but can burn hotter when in dry air. At what temperature does thermite burn and how is it actually calculated? Asked by Wiki User. White phosphorus was discovered 300 years ago when the Hamburg-based alchemist Henig Brandt boiled urine and continued to burn the residue that formed. White and red phosphorus are the most common forms. P4(s) + 5 O2(g) P4O10(s) ΔH = -3013 kJ/mol The key difference between red and white phosphorus is that the red phosphorus appears as dark red colored crystals whereas the white phosphorus exists as a translucent waxy solid that quickly becomes yellow when exposed to light.. Phosphorus is a chemical element that occurs in several different allotropes.The most common allotropes are red and white forms, and these are solid … Top Answer. Cut phosphorus under water with a knife! Phosphorus comes in several forms. 13 14 15. 1989]. 1. Log in. White and red phosphorus are monotropic allotropes – the latter is stable at all temperatures up to its melting point. Yes. White phosphorus smoke with a garlic odor is characteristic of white phosphorus burns (Eldad and Simon 1991). ... causing excruciating burns. White phosphorus is a white to yellow waxy solid with a garlic like odour. White phosphorus has a low melting point 111 F (44 C) and it autoignites at about 86 F (30 C). The incidence of burn injuries in armed conflicts varies between 2% and 18% in conventional warfare .Since World War I, white phosphorus (WP or, in military jargon, “Willie Pete”) burn injuries have been feared for their devastating consequences .Fortunately, burn injuries due to phosphorus are very rare today .. We report 4 cases of civilian white phosphorus burn injuries that … It glows in the dark because it "burns… The sand reacts with the phosphate, forming calcium silicate and phosphorus pentoxide (P 2 O 5), which is reduced by the coke to gaseous elemental phosphorus.This is then condensed into phosphorus in its white form. Munitions with the chemical can be used as incendiary weapons, to lay down smoke screens or as signals. The authors present a rare case of a 45-year-old male patient who suffered white phosphorus burns … The burns can be especially horrific as the element has a tendency to stick to the skin. In the United States, the most common causes of burns are: fire or flame (44%), scalds (33%), hot objects (9%), electricity (4%), and chemicals (3%). White phosphorus is a chemical compound known primarily for its role in munitions, though it is also commonly used in agriculture (fertilizer, insecticides, and rodenticides), fireworks, electronics (as in our case), and the industrial production of phosphoric acid. Science. White phosphorus: A waxy solid which burns easily and is used in chemical manufacturing and smoke munitions. Burns – the particles in white phosphorus when it is exploded can produce extensive burns on the human body. However, at ordinary temperatures the conversion of the white allotrope into the red form is extremely slow. Be very careful to not get phosphorus on the skin! Join now. Phosphorus is produced industrially by reacting phosphate rocks with sand and coke at high temperatures. P4 molecules are held by weak vander Waal’s forces. At any temperature above the autoignition temperature, it reacts spontaneously with oxygen producing phosphorus pentoxide with a resultant white smoke and yellow flame. . Emits a weak green light and gives off white acidic fumes of phosphorus oxides when exposed to air. Ignition temperature is high(543 K), … As such, it is frequently used by militaries around the world for its smoke producing properties to obscure or mark targets.
