Question

which method of heat transfer does not require a medium; the transfer of thermal energy by conduction and convection does not require matter; a material in which thermal energy moves easily is an insulator; materials in which thermal energy does not move easily are; the transfer of thermal energy by movement of matter is; a material in which thermal energy moves easily is an insulator true or false; the transfer of thermal energy by movement of matter is ______; the transfer of thermal energy by radiation does not require matter

Answer 1

Energy is transferred through matter by both conduction and convection. Only radiation can convey energy without the need for substance. The transfer of energy through waves is known as radiation

What is the simplest way to define radiation?

The definition of radiation is radiation that emanates from a source and moves at the speed of light through space. This energy has wave-like characteristics and is surrounded by an electric and magnetic field. Electromagnetic waves are another name for radiation.

Definitions and examples of radiation

The definition of radiation was energy that emanates from a source and moves through a substance or through space. Radiation includes heat and light. Ionizing radiation, the type of radiation covered on this website, is so-named because it has sufficient energy to knock an electron out of an atom, converting it into an ion.
