Solids are good insulators because their atoms are tightly packed, making it difficult for heat to move through them. Additionally, solids have low thermal conductivity, which means they do not transfer heat easily. The lack of free flowing particles in solids also contributes to their insulating properties.
No, insulators and conductors can be found in various states of matter. While many are solids (such as metals being conductors and plastics being insulators), there are also liquid and gaseous substances that can exhibit insulating or conducting properties.
Liquids and gases are good insulators because their molecules are spaced farther apart compared to solids, reducing the transfer of heat energy through conduction. Furthermore, liquids and gases have low thermal conductivity, meaning they do not transfer heat as easily as solids. This makes them effective insulators against heat loss or gain.
One of the best solid insulators is glass. It has high resistance to electrical current and is widely used in electrical insulators, particularly for high-voltage applications. Other good solid insulators include ceramics and plastics.
Liquids and gases are generally poor insulators compared to solids because their particles are more disordered and have higher thermal conductivity, allowing heat to transfer more easily. However, some gases like air can be used as insulators in certain applications, such as double-pane windows, where pockets of air help reduce heat transfer. Liquids are less commonly used as insulators due to their lower thermal resistance compared to gases and solids.
No, shiny surfaces are not good insulators. Shiny surfaces are reflective and do not support the absorption and retention of heat, which is a characteristic of good insulators. Good insulators are materials with low thermal conductivity that trap heat effectively.

brittle, have low electrical conductivity, and tend to be insulators.

If you think to ionic compounds:- dissociation in water- good solubility in water- as solids they are insulators- high melting point
Plastics are a good electrical insulators because they are insulators. Electricity could not pass through them unlike copper. Another good example of insulators is rubber.
Conductors and Insulators. In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
plastic, paper, wood, cardboard, and rubber are all good insulators
Conductors are good absorber of heat whereas insulator are bad absorber of heat .Examples of conductors are silver,copper,etc..and example of insulators are plastic,ebonite,etc...
diapers are good insulators because they hold in the cold and and heat but is a bad conductor
