not all non metals are good insulators only the solid non-metals

∙ 12y agoA good thermal insulator has to have tight molecules that dont let heat through good thermal insulators such as
Plastic wood cork tinfoil rubber

∙ 9y agoIonic compounds are good thermal insulators mainly due to their strong bonds. Since more energy is needed to break them, they absorb a lot of it before breaking, which creates thermal or heat energy.

∙ 11y agoCovalent compounds tend to be good insulators - example include fiberglass and ceramic materials. This is because the electrons of the molecules are locked in place and resistent to movement; this tendency insulates the electricity flowing along around them from jumping across the material.
In contrast, ionic compounds tend to be good conductors - examples include salt water and metals. This is because the electrons of the molecules are constantly being exchanged freely between different ions; this tendency allows electricity to flow along the material within impediments.

Ionic compounds often have higher melting point than metals. Using at least 2 properties of ionic compounds explain why is cookware not made from ionic compounds?
1) Ionic compounds are not good heat conductors 2) Ionic compounds are not malleable
Do Ionic compounds have poor or good conductivity?
Ionic Compounds have poor conductivity when it is solid. Ionic Compounds have great conductivity when it is either dissolved in water or is melted
How can molecular compounds be distinguished from ionic compounds?
Many ionic compounds exist as crystals but covalent compounds as molecules (there are exceptions as diamond though). Ionic compounds would be good electrical conductors unlike molecular compounds.
Does perspex conduct electricity?
Perspex is brand name for the poly (methyl methacrylate) and is not a good conductor of electricity.
What are two physical properties that differ between covalent and ionic bonds?
There are more than two. In general: Covalent compounds have low melting and boiling points while ionic compounds have high melting and boiling points. Ionic compounds are good conductors of electricity when melted, while covalent compounds are not. Ionic compounds are soluble in water, while covalent compounds are soluble in non-polar liquids. These are the essentials, but other differences exist. All of these are generalizations, exceptions do occur.
What are good thermal insulators in buildings?
Ionic compounds are good thermal insulators. Magnesium carbonate, an ionic compound, is sometimes used. Ionic compounds have extremely high melting points and therefore, if they were heated they would not melt.
What are three characteristic properties of iconic compounds?
If you think to ionic compounds:- dissociation in water- good solubility in water- as solids they are insulators- high melting point
What kinds of materials make good insulators?
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
Should the ceramic tiles on a shuttle be good thermal conductors?
No. They should be good thermal insulators.
Can you name all the good thermal insulators?
yes
Why are compounds good insulators?
it is great so i like it

What are the methods of thermal insulation?
good thermal insulators include polystyrene, plastic, rubber, and other plastic based materials.
Are good thermal insulators good electrical insulators too?
no A2: Not necessarily. Solid plastics or solid glass or ceramic have high dielectric strength but not good thermal insulation. Closed-cell foam has good thermal insulating properties but not as good a dielectric strength as solid--there are pockets of gas or air in it. The D.S. is not much better than using the same volume of gas, alone.
Do thermal insulators conduct good heat?
No. The definition of an insulator is: something that inhibits the flow of energy (heat, light, electromagnetic, electric current) from one region of space to another. Therefore thermal (heat) insulators do not conduct heat.
