What else can I help you with?
What properties most nonmetals shared?
Examples: low thermal and electrical conductivity, low hardness, they are brittle, low melting and boiling points, some are liquids or gases, low density etc.
What are the examples of conductivity?
Some examples of materials with high conductivity include metals like copper, silver, and gold. Other examples include materials like graphite, which is a good conductor of electricity due to its structure of delocalized electrons. Conversely, insulators like rubber, glass, and plastic have low conductivity.
If wood has very low conductivity does it still have low conductivity if it is very hot?
Yes, increasing the temperature of an insulator is not likely to make it more electrically conductive. Resistance generally increases as temperature increases. Some materials conduct electricity better when they are very cold, however.
Is thermocol nonconductor?
Yes, thermocol is a good insulator and is considered a nonconductor of electricity. Its low thermal conductivity makes it effective for insulation purposes in items such as coolers and packaging materials.
Which conductivity of water is better Either low conductivity of water is better or high conductivity of water is better?
Low conductivity of water is generally better as it indicates fewer dissolved ions or impurities in the water. High conductivity can be a sign of contamination or high mineral content, which may not be suitable for certain applications like electronics or drinking water.

What is the thermal conductivity of bad conductor?
Bad conductors, also known as insulators, have low thermal conductivity. This means they do not readily allow heat to pass through them. Materials like wood, glass, and plastic are examples of bad conductors with low thermal conductivity.
Is metal low conductivity?
No, metals have high conductivity but has low resistivity.
Is the flammibillity and conductivity high or low for tin?
its a high flammibillity and low conductivity
What are the physical properties of nonmetallic materials?
Nonmetallic materials generally have low electrical conductivity, low melting and boiling points, and are brittle in nature. They may also exhibit properties such as being transparent, lightweight, and having low thermal conductivity. Examples include ceramics, plastics, and rubber.
Does copper possess high or low thermal conductivity?
Copper has a high thermal conductivity, not low. This is a good generalization of any metal, although they vary in conductivity.
Do elements that have high electric conductivity also have high thermal conductivity?
Not necessarily. While there is some correlation between electrical and thermal conductivity in metals, there are exceptions. For example, diamond is a good thermal insulator despite being a good electrical insulator. Additionally, materials like ceramics can have low electrical conductivity but high thermal conductivity.
If wood has very low conductivity does it still have low conductivity if it is very hot?
Yes, increasing the temperature of an insulator is not likely to make it more electrically conductive. Resistance generally increases as temperature increases. Some materials conduct electricity better when they are very cold, however.
What are materials that have infinite conductivity at low temperatures?
Superconductors are materials that have infinite conductivity at low temperatures, typically close to absolute zero. This means they can carry electric current without any resistance. Examples include materials like niobium, magnesium diboride, and yttrium barium copper oxide.
What is non metals thermal conductivity?
Diamond has the highest thermal conductivity, and is thus used as a heat substrate in some semi-conductor assemblies. It is about 400 times that of copper. Liquid Helium may be even better, but practicality rules that out for most things.
What items contain gold?
Currency, jewelry, medicine, electronics, liquors, food. It is used in electronics because its high conductivity and low susceptibility to corrosion. It is used in currency, jewelry, food, and liquors because of its relatively rare availability. It is used in medicine for its conductivity.
