EVERYDAY SCIENCE

Detailed explanation-1: -The material that does not allow heat and electricity to pass through it. The known examples of a conductor are silver, aluminium, and iron. The known examples of an insulator are paper, wood, and rubber.

Detailed explanation-2: -An insulator is a material which does not easily allow heat and/or electricity to pass through it. Plastic, wood, rubber and glass are examples of good insulators.

Detailed explanation-3: -Insulators have crystal structure of molecules, molecules are far from each other, compared to conductors. Hence they cannot pass the heat easily through them, besides this insulators don’t have free electrons to pass heat more quickly.

Detailed explanation-4: -Overview. Thermal conductors are materials that transfer thermal energy easily. Thermal insulators are materials that do not transfer thermal energy easily. Thermal conductors are used to transfer thermal energy from one place to another.

Detailed explanation-5: -Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators. You will notice this if you have ever plugged something into a wall outlet.
