Here are a few insulators:
1.Water
2. Plastic
3. Rubber
4. Glass
5. Lead
6. Wood
7. Diamonds
8. Gases like hydrogen, oxygen, nitrogen
9. Non-metals like phosphorous, sulphur, mica
10. Some alloys like nichrome, tungsten, etc.
The most important property of metalloids is that they are god and bad conducters of heat and electicity and have good and bad amount of metalic shine. the conducter one is more important though
It is useful to heat materials when attempting to change their physical properties, such as melting or shaping. However, it may not be useful to heat materials that are sensitive to heat and may degrade or become damaged, or when temperature control is crucial for the material's stability.
Different materials respond to heat in various ways. Some materials expand when heated, while others contract. Some materials conduct heat well, allowing it to flow through easily, whereas others are poor conductors, leading to slower heat transfer. In addition, some materials may change their chemical or physical properties when exposed to high temperatures.
Heat can flow through different materials via conduction, convection, or radiation. Conduction is the transfer of heat through direct contact between materials, convection is the transfer of heat through a fluid medium, and radiation is the transfer of heat through electromagnetic waves. The rate of heat flow depends on the material's conductivity, density, and specific heat capacity.
Actually, plastic is not a bad conductor of heat and electricity, it's an insulator. An insulator is a substance that resists the flow of heat or electricity through it and plastic resists both of these.
You want materials with a low thermal conductivity. Wikipedia has a nice list:http://en.wikipedia.org/wiki/List_of_thermal_conductivities
bad conducters or poor conduct of heat and light energy
fiberglass
poor conducters of heat
they are called conducters becuse they let heat pass though them
Metals and some ceramics.
most metals are good conductors for heat.
they are poor electricity and heat conductors
yes
All metals are good conductors of heat and electricity except Mercury
Yes, most metals are good conductors of heat and electricity.
because different metals are better and worse heat conducters
