When considering the process of corrosion why is it important to carefully select metals that are to be placed together in an assembly?
When 'dissimilar' metals touch, they can create one of the prerequisites for galvanic corrosion.
Alloys are used in electrical heating devices rather than pure metals. Give reason.?
Alloys are used rather than pure metals in electrical heating devices since they have low electrical conductivity and also a low melting point. Usually the alloys don't have a single melting point; they have a range of melting points. The temperature at which melting begins is called the SOLIDUS and the temperature at which melting is complete is called the LIQUIDUS.Student
WHY CAN’T WE THROW THE ELECTRONIC DEVICES IN REGULAR DUSTBINS?
WHY CAN’T WE THROW THE ELECTRONIC DEVICES IN REGULAR DUSTBINS ? Electronic devices are made up of heavy metals like lead, mercury, cadmium, beryllium, PVC etc. If one throws e-waste in the dustbin it leads to landfills. It may leach out toxins in the soil and pollute the environment and groundwater. Electronic devices are components that are made of raw materials. So, recycling e-waste would be the better option and it leads to less energy. The fact of extracting metals and plastic from e-waste is to make more electronics but it is not at all easy. If we throw e – gadgets in the dustbin that leads to environmental pollution and unregulated groundwater supply. We are the ones who are doing this and are getting affected too. These metals are difficult to extract as most of e -gadgets used are 10 times more – energy-efficient than smelted ore. We should start recycling e-waste at least from now on. Some may think that a scrap dealer is a good option for e-waste recycling. The answer might be no. When we give our e-waste to scrap dealers, we are being a step forward to the chain of unregulated markets. These markets extract metals from devices to sell but with fewer skills and necessary safety standards may not be up to the mark. These can also be great harm to dealers who are selling and it causes environmental pollution. By performing 4 Rs a consumer can recycle e-waste Reuse: Use gadgets for longer. Then upgrade to a new e – gadget if you ideally think there’s no necessity. Repair: Do note that you have a recovery policy. If you don’t then that may be a problem as when you want to give for the repair you won’t get any warranty. Recycle: Talk to the brand you had purchased. Discuss with them. Discuss the return policy. Most brands have information on their websites. You can also go through it. Research: Here’s a near R called research added by Sushmita Pai (Head of Outreach at Swachh, Pune). What we need to look for is something for bio-compostable within a period. Everything is biodegradable at its own time and ultimately brands accepting this Research is also important. If the brands sell then it gets a larger presence. So, E-waste depends on how brands convey it. Till 2020 E-waste had generated 3 million tons and it will increase rapidly and exponentially. In this meantime, of this Research, we consumers can give attention to e-waste recycling. A good mindset is all needed for this Implementation. Its important us to remember that tossing out electronics instead of recycling does lot of harm to environment and to us. If in our country doesn’t support that law also, we shouldn’t throw e-gadgets in dustbins. Instead, we need to recycle them. We can give the e – gadgets to Great lakes Electronics Corporation who have an experience from years. It is a friendly recycling in electronic products field. The team of this Corporation dismantle the parts and if there is any use then they send them for metal recovery or else those are sold to reuse.
What are the 3 categories metals go into?
Metals, Non-metals and Metaloids
What are the characteristics of sheet metals that are important in sheet-forming operations?
The alloying elements and the metal tempers -W (as quenched/solutionised),O (annealed),T (tempered)
What characteristic makes some metals important in electronic devices?
They are conductors
What metals and non metals are used in computers and electronic devices?
Metals commonly used in computers and electronic devices include copper (wiring), gold (connectors), aluminum (heat sinks), and iron (steel casing). Non-metals like silicon (semiconductors), carbon (plastic components), and oxygen (used in insulating materials) are also essential in electronic devices.
What pollutant is associated with electronic equipment discarded in landfills?
Several metals, including lead and mercury, are included in electronic devices that should be recycled and not disposed of in landfills.
What electronic component was widely used in electronic devices before solid state components were developed?
Elements found between the metals and nonmetals are called metalloids. Hope that helped!
Is germanium a non metal or metal or metalloid?
Germanium is a metalloid. It exhibits properties of both metals and non-metals, making it a semiconductor commonly used in electronic devices.
Which materials is not a good insulator?
Metals are not good insulators as they have high thermal conductivity, allowing heat to pass easily through them. This is why metals are commonly used as conductors in electrical circuits or as heat sinks in electronic devices.
Bacteria are not used to make?
Bacteria are not used to make larger electronic devices like smartphones or computers. These devices are typically manufactured using a combination of metals, plastics, and other materials that are not produced by bacteria.
What group is 32 on the periodic table?
The element found in group 32 on the periodic table is Germanium. It is a metalloid that can be found in some minerals and is used in electronic devices.
Are non metals semiconductors?
Metals are conductors. Semiconductors are usually non-metals or metalloids.
How do you use semiconductor in a sentence?
Semiconductors are crucial components in electronic devices like computers and smartphones, enabling the flow of electric current in a controlled manner.
Major import and export products of japan?
•Top 10 Imports (Japan from world) crude oil, textile articles, electronic components, computers, LNG, fishes and shells, audio and visual apparatus, nonferrous metals, optical instruments, petroleum products.
Why is beryllium classified as an aklaline metal?
Because beryllium has some similarities with the other alkaline earth metals; and also the electronic configuration is important.
