Heating elements A typical heating element is usually a coil, ribbon (straight or corrugated), of strip of wire that gives off heat much like a lamp filament. When an electric current flows through it, it glows red hot and converts the electrical energy passing through it into heat, which it radiates out in all directions.

Flame tests The inner core of the candle flame is light blue, with a temperature of around 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red. The further you reach from the center of the flame, the lower the temperature will be.

- The hotter a hydrocarbon gas burns, the bluer the flame. An orange flame indicates a cool flame with incomplete combustion since soot (unburnt carbon) glows orange.   … Hydrogen gas burns so completely and so hot that it emits light in the ultraviolet. You cannot see a hydrogen gas flame.

What is the hottest object in the universe? I think the radiating area of a quasar must be the hottest natural thing in our present universe, since it emits the greatest amount of energy from a single source of anything we've ever discovered. (Though I note that no quasar has ever been discovered which is nearer than about 10 billion light years, meaning they were phenomena of the universe at a very young age, and none really exist contemporary with us today).

At what temperature does thermite burn? Posted 8 November 2010 - 09:34 PM. I know that Dicyanoacetylene (carbon subnitride) combusts at a flame temperature of 4990C. This is hot enough to melt almost all metals, except maybe some superalloys.

What Gives Gold that Mellow Glow? With an atomic number of 79, gold is in the last row of the periodic table containing stable elements, and only four stable elements (mercury, thallium, lead, and bismuth) have greater atomic number.With 79 protons in its nucleus, the electrons of the gold atom are subjected to an intense electrostatic attraction.ith a single 6 s electron, you might expect gold to be highly reactive; after all, c sium has the same 6 s 1 outer shell, and it is the most alkaline of natural elements: it explodes if dropped in water, and even reacts with ice.

What is the hottest star? (solar system)? The hottest blue stars are about 40,000 degrees at the surface, and many millions at the core-much hotter than the sun, which is 16 million in the core. We measure star temp at the surface, however, so the sun is a relatively cool star at about 4500 degrees on the surface. The Sun is the only star in our solar system. Vega and Rigel are hot blue stars in the constellations Lyra and Orion. eri · 9 years ago.

Period 6 element Caesium is an alkali metal and has physical and chemical properties similar to those of rubidium and potassium. The metal is extremely reactive and pyrophoric, reacting with water even at −116 °C (−177 °F). Caesium is one of the most reactive elements of all, even more reactive than fluorine, the most reactive nonmetal.

Rubidium Facts - Rb or Element 37 Properties: Rubidium may be liquid at room temperature. It ignites spontaneously in air and reacts violently in water, setting fire to the liberated hydrogen. Thus, rubidium must be stored under dry mineral oil, in a vacuum, or in an inert atmosphere. It is a soft, silvery-white metallic element of the alkali group.Rubidium forms amalgams with mercury and alloys with gold, sodium, potassium, and cesium.Rubidium glows red-violet in a flame test. Rubidium can be used to give fireworks a red-violet color. 2  Rubidium is the 23 rd most abundant element in the Earth's crust. 3  Rubidium chloride is used in biochemistry as a biomarker to track where potassium is taken up by living organisms.

Do You Know What Will Not Burn In A House Fire? However in many cases, there are a select few items that withstand the inferno. The average house fire burns at a temperature of about 1,100 degrees Fahrenheit, which isn’t hot enough to destroy most metals and earthly-made substances. And if an item is well-placed and small in size, its chances of survival increase drastically.

Stellar nucleosynthesis As the star ages and the core temperature increases, the region occupied by the convection zone slowly shrinks from 20% of the mass down to the inner 8% of the mass. The type of hydrogen burning process that dominates inside a star is determined by the temperature dependency differences between the two reactions. The pp-chain reaction starts at temperatures around 7006400000000000000♠4×106 K, making it the dominant mechanism in smaller stars.

What is the hottest flame color of all? Color is light, and light is a wave with energy. The higher the energy (in this case taking the form of heat), the shorter the wavelength and corresponding color. Blue is the highest energy light that humans can see, and therefore blue must be the hottest color of a flame. Raafiq · 6 years ago.

All About Anthracite Coal The coal is slow-burning and difficult to ignite because of its high density, so few pulverized, coal-fired plants burn it. Heating value: Anthracite burns the hottest among coal types (roughly 900 degrees or higher) and typically produces approximately 13,000 to 15,000 Btu per pound.
