Flame Test: Flame test is a qualitative test used to identify the presence of certain metal ions in the solution. The vapors or gas particles containing the ions may be excited by the heat. Upon relaxation, energy is emitted and this has a characteristic wavelength and...
5. Acrylic yarn fabric is lighter in synthetic fabric than polypropylene fiber, so it is a good light clothing material, which can be used to make mountaineering clothes, winter warm clothing, etc. When testing polyester with the same method, once contacting with the flame, it will first caus...
In principle, it isa controlled flame test with the intensity of the flame color quantified by photoelectric circuitry. The intensity of the colour will depend on the energy that had been absorbed by the atoms that was sufficient to vaporise them. The sample is introduced to the flame at a c...
A lighter is a portable device which generates a flame, and can be used to ignite a variety of items, such as cigarettes, gas stoves, fireworks, candles or campfire. It consists of a metal or plastic container filled with a flammable liquid or compressed gas, a means of ignition to prod...

radiation that is considered from the point of view of its ability to excite the human visual system.' The CIE provides two interesting notes to this formal definition of light: 'NOTE 1—This term has 2 meanings that should be clearly distinguished. When necessary to avoid confusion between ...
Lilac point Siamese.They have white bodies with pinkish-gray points that appear lilac in color. Lynx point Siamese.This type has lynx/tabby (striped) points on its body, regardless of color. Flame point Siamese.Also called red point Siamese, it is a rare Siamese breed with orange coats and...
Ammonia was found to be a result of ammonium starch phosphate carbamates decomposition and, as inert gas, aids in flame extinguishment [109]. Moreover, other natural derivatives and bio-macromolecules, such as proteins and casein, a phosphorylated protein derived from renewable precursors, find ...
Finally, it should be highlighted that warm and humid environments may create ideal micro-environments for the colonisation of biodeteriogens, such as fungi and bacteria [69]. The presence of micro-organisms infestation has been cited in multiple case study evaluations but their action, the ...
natural gas smell similar to sulphur or rotting eggs. The stronger this smell, the more likely it is that you have a gas leak. You may get a slight whiff of this smell when turning on an older gas grill, butmost energy-efficient grillsmade in the last 15 years should not produce an ...
