An example of inert gas is argon, which does not react with the molten weld. It is the most commonly used shielding gas in TIG welding. Carbon dioxide and oxygen, however, do react with the molten weld as does a mixture of carbon dioxide and argon. Helium (He) is also an inert shiel...
Plastics are a type of resin that can be easily molded and are often used as a cheap, durable packaging material. There are six major varieties of plastics commonly in use. Some plastic items are made of a mixture of different resins. High-density polyethylene, also known as HDPE, is a ...
How Does Insert Molding Work? Molten resin is injected into a plastic mold that has been custom-made to fit the part’s geometric parameters. Plastic resins are injected and allowed to solidify in the mold. They are then ejected from the insert mold. The primary distinction is that the meta...
A cell is transferred from an isotonic solution to a hypotonic solution. What happens to the cell? What percentage of sodium is in pure table salt? Why does the molten sodium chloride conduct electricity, but the solid form of sodium chloride does not?
First a charge is prepared where a mixture of raw materials is melted down to make an alloy. Prime aluminum is added, and once all the prime aluminum has melted, scrap is added to remove moisture. Methods and techniques for treatment of molten aluminum increase and verify its purity. This ...
Most PV modules — likesolar panelsand shingles — contain at least several and up to hundreds of wafer-based crystalline silicon solar cells. (Source:EIA) How Does a Wafer-Based Solar Cell Function? A wafer-based solar cell is a unique type of non-mechanical semiconductor that uses a p-...
In a copper cycle lab if I add HCl to CuO to produce CuCl, what would a word equation for that reaction be? Is it a chemical reaction? What complexes are observed for that step? What does that meanWhat reaction will take ...
A mixture containing two or more metallic elements or metallic and nonmetallic elements usually fused together or dissolving into each other when molten; Brass is an alloy of zinc and copper Brass (informal) Impertinent, bold: brazen. Alloy The state of impairing the quality or reducing the value...

the lava comes up from the mantle (which is the layer under the surface). Once there's enough molten rock — called magma — and enough pressure on it, a volcanic eruption occurs. In many volcanoes, the magma rises up through a central tube or "throat," and emerges out the top of ...
