not all non metals are good insulators only the solid non-metals
What else can I help you with?
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?
Cookware needs to have good thermal conductivity, while ionic compounds have poor conductivity. Additionally, ionic compounds are brittle and prone to shattering when subjected to mechanical stress, making them unsuitable for cookware that requires durability and resistance to impact.
Why is cookware not made from ionic compounds?
Cookware is not made from ionic compounds because these compounds tend to be brittle and can crack or shatter when subjected to heat or sudden temperature changes. Metals like stainless steel, aluminum, and cast iron are preferred for making cookware because they have good thermal conductivity and are durable.
Do Ionic compounds have poor or good conductivity?
Ionic compounds have good conductivity when in solution or molten state because the ions are free to move and carry an electric charge. However, in solid form, ionic compounds have poor conductivity because the ions are held in fixed positions and cannot move to carry a charge.
What types of compounds are good electrical conductors in the liquid state?
Ionic compounds are good electrical conductors in the liquid state.
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.
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.

What makes good thermal insulators and conductors?
Good thermal insulators have high thermal resistance and low thermal conductivity, which helps to slow down heat transfer. Materials like foam, fiberglass, and wool are good insulators. Good thermal conductors, on the other hand, have high thermal conductivity and allow heat to transfer quickly. Copper, aluminum, and silver are examples of good thermal conductors.
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
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.
Why is cookware not made from ionic compounds?
Cookware is not made from ionic compounds because these compounds tend to be brittle and can crack or shatter when subjected to heat or sudden temperature changes. Metals like stainless steel, aluminum, and cast iron are preferred for making cookware because they have good thermal conductivity and are durable.
Is shiny a good insulator?
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.
Are napkins insulators?
Napkins are not good insulators, as they are thin and do not provide much thermal or electrical resistance. They are more commonly used for wiping and cleaning purposes.
What matirials are good insulators except foam?
Some other materials that are good insulators are wood, rubber, glass, and fiberglass. These materials have low thermal conductivity, preventing the transfer of heat.
