Question

What is called for the materials that restricts heat flow by radiation, conduction and convection ? ​

Answer 1

Answer:

hope my answer is correct

Explanation:

Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation . No mass is exchanged and no medium is

Answer 2

Thermal insulators.

Explanation:

• Thermal insulators are materials specially designed to reduce the heat flow .
• It is done by limiting  conduction, convection, or both.
• The property by which a material resist heat flow to temperature difference is called thermal resistance.
• The property of a material that characterizes its ability to prevent radiation heat transfer is called surface emissivity.
