What are 5 insulators?
Insulators oppose electrical current and make poor conductors.
Some common conductors are copper, aluminum, gold, and silver.
Some common insulators are glass, air, plastic, rubber, and wood..

What’s the most conductive metal?
SilverThe six most conductive metals to consider include: Silver: The single most conductive metal, silver conducts heat and electricity efficiently thanks to its unique crystal structure and single valence electron.
What is the best insulator?
A: The best insulator in the world right now is most probably aerogel, with silica aerogels having thermal conductivities of less than 0.03 W/m*K in atmosphere. of aerogel preventing ice from melting on a hot plate at 80 degrees Celsius! Aerogel has its amazing properties because it’s mostly made out of air.
Is plastic a good insulator?
Plastic Insulator Becomes a Heat Conductor. … Plastics are excellent insulators, meaning they efficiently trap heat—a quality that is an advantage in something such as a coffee cup sleeve.
Which metal is best conductor of heat?
silverTo my knowledge, silver is the best conductor of both heat and electricity among metals with a thermal conduction value of about 430 W/(mK). Gold and copper both come respectably close to silver, and with Copper being significantly less costly it is often chosen over silver in many applications..
What are 5 good conductors?
Is wax a good insulator?
Paraffin wax is an excellent electrical insulator because it has a higher resistivity and it seldom conduct electricaity.
Which is a better conductor silver or gold?
The most electrically conductive element is silver, followed by copper and gold. … Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance.
Is Diamond a good conductor of electricity?
In diamond, all four outer electrons of each carbon atom are ‘localized’ between the atoms in covalent bonding. The movement of electrons is restricted and diamond does not conduct an electric current. Thus, graphite is a good conductor and diamond is not.
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 is the strongest conductor of electricity?
Silver also has the highest thermal conductivity of any element and the highest light reflectance. Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance.
What are 3 good conductors?
Conductors conduct electrical current very easily because of their free electrons.Insulators oppose electrical current and make poor conductors.Some common conductors are copper, aluminum, gold, and silver.Some common insulators are glass, air, plastic, rubber, and wood.

Is Fur a good insulator?
In many situations, we want to trap heat and slow down its flow, or stop the flow of electricity and prevent electric shocks. Plastic, rubber, wood, and ceramics are good insulators. … Air is also a good insulator of heat. Animal fur traps warm air close to the creature’s skin to keep it warm.
Which metal is a poor conductor of electricity?
Bismuth and tungsten are two metals which are poor conductors of electricity. There are many, but some include Aluminum, Bismuth, Gallium, Indium, Lead, Thallium, Tin, Ununhexium, Ununpentium, Ununquadium, and Ununtrium.
What is harder than diamond?
Scientists have calculated that wurtzite boron nitride and lonsdaleite (hexagonal diamond) both have greater indentation strengths than diamond. Source: English Wikipedia. (PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world.
Can diamonds stop a bullet?
Diamonds are hard, but brittle, so sufficient force would crack the diamond. The same thing happens with bullet-proof vests. … the bullet dissipates energy when cracking the ceramic and stops, since the ceramic is super hard and resists the bullet grinding it’s way through it.
