Because of the molecules they are made up of. Some metals contain atoms that flow nicely together so that heat just zips through, but others (especially composite metals like brass or steel) make the heat sort of 'bounce around" off the molecules, taking longer to heat up. Diamonds and crystals are the best for conducting heat because it just goes right through, doesn't bounce off anytrhing. Other good metals are copper and tin

Silver is the best conductor for electricity and heat. But because the price for siver is expensive, we usually use copper (electricity), iron (heat), and aluminum (both).

∙ 10y agowell because the particle theory, the conduction makes the conductors have small particles or big so the big ones move faster so they are conductors and the small ones are the insulators

∙ 12y agometals can conduct electricity better than non-metal due to partially filled 3d orbital and also 4s orbital and also because of high charge and small atomic size

What does an electrical insulator have?
Electrical insulators are made from materials that are poor conductors of electricity. Metallic elements are good conductors, non metallic elements are poor conductors. Some materials used as insulators are, paper, glass, ceramics, rubber and plastics.
Which 3 materials reflects light?
ANY material reflects light. Some do so better than others.
What is a material that cuts down the flow of current but does not stop it?
The Materials are of three kinds:- Conductors- Semiconductors and- InsulatorsThe Insulators have the property to stop the flow of electricity, because they have less number of free electronics... by: gloria & tatiana
Are all conductors of electricity magnets?
No, some materials (water, for example) conduct electricity and are incapable of becoming magnetic.
What are the classification of materials according to electrical conductivity?
Most substances fall into two categories - conductors and insulators. Conductors are those which electricity can pass through relatively easily. Metals are the usual example, but other substances such as graphite and polar liquids such as water are also good conductors. Insulators are poor conductors: those that electricity cannot pass through easily. Most plastics are insulators. Some substances fall in between: these are semiconductors, which allow electricity through in some instances, but not in others. This property makes them very useful in electronics. Some substances can be such good conductors that, under some circumstances, they can allow electricity to pass through them with no resistance at all. These are called superconductors.
What are the conductors of a circuit?
Everything - it wouldn't conduct at all otherwise. Some materials conduct better than others, like the conducting wires.
Metals are conductors of heat and electricity?
Yes, but some metals are better conductors than others.
Why are some kinds of metals conductors of electricity and some are not?
All metals can conduct electricity, though some better than others.
What materials can produce sound waves?
Every material transmits sound. Some better than others.
Why are some conductors better than others?
well because the particle theory, the conduction makes the conductors have small particles or big so the big ones move faster so they are conductors and the small ones are the insulators
What are some materials that are good conductors?
metals like iron and copper These are good conductors of both heat and electricity.
Why some of the materials are insulators?
They are bad conductors ,they do not allow heat transfer.
Is a metal and nonmetals are both good conductors?
Metals are good conductors. Some non-metals are good conductors, but many others are not.
What materials heat up faster?
Materials that heat-up faster are known as conductors. Silver, Copper, Gold and Aluminium are some conductors that have the ability to transfer heat.
What does an electrical insulator have?
Electrical insulators are made from materials that are poor conductors of electricity. Metallic elements are good conductors, non metallic elements are poor conductors. Some materials used as insulators are, paper, glass, ceramics, rubber and plastics.
What are some materials used to test a simple circuit for conductors and insulators?
Battery,Tester
Which 3 materials reflects light?
ANY material reflects light. Some do so better than others.
