What is a foam cup conductors or insulators?
Foam cups are typically insulators because they are made of Styrofoam, which is a material that does not conduct electricity well. This means that foam cups are not good conductors of heat or electricity, making them effective at keeping hot drinks hot without transferring heat to your hand.
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 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.
Why are foam and fiber glass good heat insulators?
Foam and fiberglass are good heat insulators because they have low thermal conductivity, meaning they do not easily conduct heat. The air pockets within foam and the composition of fiberglass trap heat, creating a barrier that slows down the transfer of heat. This makes them effective at keeping spaces insulated and maintaining temperatures.
Is popsicle sticks good insulators?
Popsicle sticks are not effective insulators because they are poor at reducing heat transfer. Insulators are materials that prevent the flow of heat, and popsicle sticks do not provide a significant barrier to heat transfer due to their low thermal resistance. Materials like foam or fiberglass are better insulators than popsicle sticks.

A good electrical insulator?
Two good Insulators are foam and styrafoam
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 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.
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.
What makes a good insulator of cold?
Good insulators of cold typically have low thermal conductivity, which means they do not allow heat to easily transfer through them. Materials with a lot of trapped air pockets, like foam or fiberglass, are good at preventing the movement of heat. Additionally, materials that are thick and dense can also be good insulators of cold.
Are metals usually used as heat insulators?
No, metals are not typically used as heat insulators. Metals are good conductors of heat, which means they can easily transfer heat rather than insulate against it. Materials like wood, fiberglass, and foam are commonly used as heat insulators instead.
