Why does radiation not require other particles?
Because radiation is particles.
Which of the heat transfers does NOT require the presence of particles?
radiation
Why can heat travel through space by radiation but not by conduction or convection?
Because conduction and convection require particles to transfer heat. Space is a vacuum (has no particles in it) so convection and conduction cannot occur.
Does radiation require the presence of particles of matter?
Not necessarily.If you are referring to the spectrum of electromagneticradiation like gamma, X, UV, visible, infra red, thermal,microwave, shortwave, radio/TV waves, they are pureenergy radiation.If you are referring to the radiation emitted by radioactiveelements you have:Alfa radiation. Consists of high energy (kinetic energy)helium nucleus (particles).Beta radiation. High energy (kinetic energy) neutrons (particles).Gamma radiation. Very small wavelength Electromagneticradiation (pure energy).
Why cant thermal radiation move through space by conduction or convection?
Because in space there are no particles (this is called a vacuum), however conduction and convection require particles to work eg. solids, liquids and gases have particle arrangements. So thermal radiation has to travel through space via radiation as space is a vacuum and particle-less.
Why does radiation not require other particles?
Because radiation is particles.
Which of the heat transfers does NOT require the presence of particles?
radiation
What roles do radiation play in heating and cooling the earth?
Radiation transfers heat from one object to another. It does not require any particles unlike conduction and convection. Radiation travels in the form of electromagnetic waves.
What helps keep a penguins skin dry?
Radiation is a type of heat transfer that does not require particles . how does the color of the penguin skin help it?

Is radiation a measure of the average kineic energy of the particles in an object?
No, radiation is not a measure of the average kinetic energy of particles in an object. Radiation refers to the emission of energy as electromagnetic waves or particles from a source. The energy of radiation can vary depending on the type and source, and it is not directly related to the average kinetic energy of particles in an object.
Is there particles in radiation?
yes
Does heat radiation require a medium to travel?
Radiation does not require a medium.
What happens when an unstable nucleus undergoes radioactive decay?
Particles or electromagnetic radiation are emitted.
Radiation that is similar to x-rays and is not composed of particles?
gamma radiation
