What is the softest mineral on Earth?
TalcTalc is the softest and diamond is the hardest.
Each mineral can scratch only those below it on the scale..
What fabric is stronger than Kevlar?
Bulletproof polytheneIt’s the mundane stuff of plastic bags and sandwich boxes, but polyethylene has a more streetwise talent: in the form of dense, high-molecular-weight fibres it can stop a bullet in its tracks.
What is the strongest fabric in the world?
At DESY’s X-ray light source PETRA III, researchers have produced the strongest bio-material that has ever been made. The artificial, but biodegradable cellulose fibers are stronger than steel and even than dragline spider silk, which is usually considered the strongest bio-based material.
What is the strongest fiber?
Spider silkSpider silk is famous for its amazing toughness, and until recently a tensile strength of 1.3 gigapascals (GPa) was enough to earn it the title of strongest natural material.
Can you break a diamond with a hammer?
To say something is “hard” is not the same as saying it is “strong”. As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. … This makes the diamond incredibly hard and is why it is able to scratch any other material.
Which is stronger silk or cotton?
Which is stronger silk or cotton? … Silk is a natural, strong fibre as it has great tensile strength, which allows it to withstand a great deal of pressure. Cotton is also a strong fibre but the strength is largely affected by moisture, as its wet strength is 20% (much higher than dry strength).
Which is the weakest natural Fibre?
WoolSilk is the strongest of all the natural fibres and Wool is the weakest of all natural fibres.
What is the weakest gem?
talcIt’s a bit of a trick question. The weakest MATERIAL is talc. This is drilled into every geology & geography student when learning Mohs Scale. A mineral has to be strong enough to be cut and polished to be a gemstone.
Are Diamonds bulletproof?
Diamond Armor is certified bulletproof by NATO standards, waterproof thanks to nano-technology sealing and has an EMPA air conditioning system in-built to keep the wearer cool.
What happens if you melt a diamond?
At ~700 degrees Fahrenheit the diamond will start burning. This will produce Carbon Dioxide and change the structure so that it is no longer a diamond. As diamond is made of Carbon, it would revert back to that form while losing its mass to the production of CO2. This is due to the presence of Oxygen.
Is Obsidian stronger than diamond?
Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts. … Obsidian is found all over the world.
What are the most tightly woven fabrics?
Some cotton fabrics are more tightly woven than others. Examples of tightly woven cotton include denim, cotton sateen, percale, and poplin. Bedsheets are a good place to find cotton percale and sateen. I recommend getting light to medium weight fabric for easier breathability.
What is stronger than a diamond?
Boron NitrideMuch like carbon can be assembled into a variety of configurations, Boron Nitride can take on… [+] The structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications.
What is the weakest material on earth?
According to the Mohs scale, talc, also known as soapstone, is the softest mineral; it is composed of a stack of weakly connected sheets that tend to slip apart under pressure.
