3. the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
6. the throwing back by a body or surface of light, heat, or sound without absorbing it.
7. Radiation is energy that comes from a source and travels through space at the speed of light.
8. a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this.
9. radiation, a region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers (nm) to 1 millimeter (mm).

1. the process or action by which one thing absorbs or is absorbed by another.
2. waves, waves that are created as a result of vibrations between an electric field and a magnetic field.
4. Any material that keeps energy such as electricity, heat, or cold from easily transferring through
5. the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
7. energy, Radiant energy is the physical energy resulting from electromagnetic radiation, usually observed as it radiates from a source into the surrounding environment.
8. where heating occurs by currents in a fluid
