Guide to Metal Melting Points (ºF)

Depending on your project, melting point can play a key role in the material you choose. Anything from forging high-temperature applications can drastically change your decision. Online Metals is here to provide a quick walkthrough of the wonders of melting points. Each alloy and material have a range of temperatures with lower end of the […]

Make Sodium Metal Without Electrolysis Using Domestic Chemicals

Warning: Sodium is a highly reactive and flammable metal. This reaction also uses high temperatures and generates flames. Fire safety protocols must be in place. Dioxane is carcinogenic. Wear gloves when handling it and work outside or in a fume hood. Greetings fellow nerds. Sodium metal is quite famous among chemists as well the general […]

6. 11th Class Physics Lecture | Current Electricity | Drift Velocity of Free Electrons (GA)

let us study about drift velocity of free electrons. we have discussed that in the situation of conductor when, a battery is connected across it. and, the circuit is closed. You can just have a look on the situation i am drawing here. this a battery which is connected across cylindrical conductors wire switch. as […]

Why Does Metal Rust? – Reactions Q&A

Well folks, you asked and we’re answering. That’s right we heard you. Peter Sterckx wants to know why do metal things grow. Well, here’s Sophia with an explanation. Corrosion is caused by a redox reaction, which is actually two simultaneous reactions in one: Reduction and Oxidation. (Oncscreen: 1) Reduction) A reduction reaction occurs when some […]

Make Sodium Metal with Menthol (and a bunch of other stuff…)

Warning: Sodium is a reactive flammable metal. Wear gloves when handling it. Fire safety protocols must be in place. Greetings fellow nerds. Sodium is a very famous and interesting metal that’s highly reactive even with water. It’s tremendously useful in chemistry for such purposes as reducing other compounds or drying solvents. However, being rather dangerously […]

Electrolytic Refining of Metals | #aumsum

Our topic for today is Electrolytic Refining of Metals. Nice Jacket. Thank you. Hey. My Jacket. Our last participant is Mr. Smart. Electrolytic refining is the process of obtaining pure metals like gold, silver, copper etc. by the process of electrolysis. Electrolytic refining of copper. Take an electrolyte of acidified copper sulfate solution. Take the […]

Energy & Electricity in Science : How Does Optical Fiber Work?

Hi I’m Steve Jones and I’m going to show you how an optical fiber works. In England we spell fiber bre and I know in America ber. First of all looking at a more traditional thing this is a solid prism of glass. A prism triangular in this case, 45 degree, 90 prism of glass. […]

What Are Metallic Bonds? | Properties of Matter | Chemistry | FuseSchool

Metals are used in many everyday objects. This morning when I woke up I decided to have a soft-boiled egg and a cup of coffee. The pot I used is made of metal. The kettle is made of plastic, but the coiled heating element inside it is made of metal. Metals are good conductors of […]

Energy & Electricity in Science : How Does Electricity Light Up a Bulb?

Hi, I’m Steve Jones and I’m going to tell you how electricity lights up a bulb. Well, the bulb doesn’t really light up unless there is a coating on it, it is the filament inside which lights up and the filament is made usually of something called tungsten which is a very hard material and […]
