What else can I help you with?
What are 3 examples of insulators?
examples plastic Rubber oil
What material traps air best?
Materials with low thermal conductivity, such as wool, down feathers, and foam, are good at trapping air. These materials create pockets of air that act as insulators, preventing heat from escaping and helping to keep you warm.
What substances are the best insulators?
Usually nonmetals. Rubber, plastic, wood, cloth, paper, Styrofoam, tinfoil (to reflect the heat.)The most common insulator for electricity is plastic.
What are three good insulators of heat?
Three good insulators of heat are, maybe plastic, wood and glass! That's all I can think of right now but plastic and wood are very good insulators (etc. used of saucepan handles)
What are good insulators?
Good insulators include glass, styrofoam, plastic, wood, rubber, cloth, air, glass, and etc. It really depends on what you want to use it for. For example, fiberglass or styrofoam works the best as heat insulators. And rubber or glass as electric insulators.
What are 5 electrical conductors and 5 electrical insulators?
Enorder for materials to conduct electricity they need to have free electrons which carry the current. Materials which can do this include metals, water, Ionic salts when in there molten or aqueous states. Wood, plastic, gases and covalent compounds do not have free electrons and therefore do do conduct.
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.
What insulators would be found in a house?
Common insulators found in a house include fiberglass, cellulose, foam board, and reflective foil. These materials are often used in walls, attics, and floors to help regulate indoor temperature and reduce energy loss.
What are some heat insulators?
Some heat insulators are fiberglass, polyurethane foam, and polystyrene. Two other thermal insulators used as insulating materials in building construction are mineral wool and cellular glass.
What types of materials does heat not travel through?
Heat can and does travel through all matter. It's just that some materials carry it much slower than others, and these are called insulators. The best ones being foam type materials.
Why is plastic foam fur and feathers bad conductors of heat?
Plastic foam, fur, and feathers are bad conductors of heat because they have a lot of air pockets trapped within them. Air is a poor conductor of heat, so materials that have a high amount of air trapped within them are also poor conductors of heat. This trapped air creates a barrier that prevents the easy flow of heat, helping to insulate the object or organism.
What is the freezing point of a pillow?
For feathers, foam plastic, cotton ... all well above the boiling point for water.
