Which materials are typically used as thermal insulators? check all that apply. copper foam ceramic wood plastic if any one needed the answer to this the answers are foam, wood, and plastic i just took a quiz on it. and i know this is a question but i wanted to give you guys the answer because i couldn't comment on the other ones. you and i hope you get it correct.

Thermal insulators are those materials which do not allow heat or thermal energy to pass through them. In other words, they are poor conductor of heat.

Thermal insulators are- Wood, plastic, ceramic, and foam. They do not pass the heat from one object to another object.

Although most of the ceramics are considered as good thermal insulator ( due to the absence of free electrons) but very few ceramic are not thermal insulators like- cubic boron nitride.

The correct options are foam, ceramic, wood and plastic.

Thermal Insulators can be defined as the substances that does not allows the heat to pass through them and lock the heat inside them only.

These substances protect the heat from coming out and keep the substances warm.

Heat can transfer from one place to another by the process of conduction, convection and radiation. Insulators protects from the heat loss caused due to conduction.
