Transmission of heat by radiation is due to the fact that bodies with a temperature higher than absolute zero emits photons (light) with a spectrum (distribution of energy among different color, considering also infrared, UV, X rays and so on) dependent on the body material constitution and on temperature.
Remember that for photons a relationship exist between frequency (color) and energy: higher the frequency, higher the single photon energy.
Thus higher the temperature higher the average emitted photon energy and higher the emitted spectrum average frequency.
While emitting hot bodies slowly loose energy and cool.
These photons are absorbed by other bodies, more and more efficiently while temperature of the absorbent bodies is lower and lower. When absorbed, they are transformed in heat again rising the temperature of the absorbent body.
Thus, at the end, hot bodies preferentially emits photons and cool and cold bodies preferentially absorb photons and rise temperature.
What else can I help you with?
Is the emission of electromagnetic radiation by an excited atom a wave or particle theory?
wave theory of light
Heat energy is transferred from the hot end of a metal wire to the cool end through?
Heat conduction, by means of particle collisions transferring energy.
How does the particle theory relate to the thermos?
thermal energy is energy caused by friction friction is when two or more objects touch kinetic energy is when somthing is falling after you realesed potential energy that's all i can tell ya
Why is vacuum the best thermal insulator?
Heat travels in 3 ways. Conduction, convection and radiation. Conduction is the transfer of heat through collision of particles. Convection is the transfer of heat through the movements of particles (ie. hot particle rises, cold particle sinks). Vacuum is made up of nothing (when there is no particle, it is vacuum), and so, it is unable to transfer heat through conduction and convection at all, making it the best thermal insulator
Evaporation using particle theory?
The Particle theory maintains that particles move more rapidly as they get more warm. As the continue to heat up, they become less dense and move even more. As this process continues, the particles expand and separate which changes their state from liquid to gas.
Is the emission of electromagnetic radiation by an excited atom a wave or particle theory?
wave theory of light
Who discovered the particle theory of radiation?
Neils Bohr
What are the problems with the particle theory?
Electromagnetic radiation sometimes behaves like waves - for example, interference.
What are the most important postulates in the Particle Theory in regards to heat?
eatoms and nucleus
What is the transfer of heat from particle to particle called?
the process by which heat can be transffered from one particle of matter to another is called conduction.in this process ,,the heat absorbed at one particle is transferred to a neighbouring particle contrary to the process called convection where the particles move themselves .an example of conduction : when u heat a rod at one end , after sometime u can feel the heat at the other end as well.
Theory of electromagnetic radiation?
James Clerk Maxwell came up with the Theory of Electromagnetic Radiation.He stated that, "When electrically charged particle moves under acceleration, alternating electrical and magnetic fields are produced and transmitted in the forms of waves called electromagnetic waves or electromagnetic radiation."This is the Theory of Electromagnetic Radiation.
What are the type of heat?
the 3 types of heat transfer is conduction, convection, and radiation. conduction is when molecules transfer their heat to other molecules when they bump into each other. heat transfers through solids. metals are the best conductors. convection is when energy is transferred by the movement of energy from a hotter, less dense particle to a colder, denser particle. heat transfered through liquids and gases by circulating currents. these currents are called convection currents. radiation is when heat transferred through space. thermal energy is transferred in waves. heat radiation is also called infrared radiation. the sun sends its heat through radiation.
What is the name for the particle theory?
The particle theory is called the "particle model" or "particle theory of matter." It proposes that all matter is composed of tiny particles that are in constant motion.
How does the particle theory relate to heat transfer?
the amount of "heat" that a particle has is really dependent on how fast that particle is moving. Heat is really just the motion of particles. So, one particle can transfer heat (motion/speed) to another by colliding with it. Just like a someone throwing a billiard ball into a second billiard ball. Before the 2 balls collide, the one you threw (moving faster) is the hot particle and the stationary ball (not moving/slow) is the cold one. After the collision both balls will be moving. So some heat (motion) was transferred from one ball to the other. When you fry bacon on a stove, the fast moving particles of the pan collide with the bacon particles, causing them to move faster. If the bacon particles move faster, they are hotter. NOW GO READ YOUR CHEMISTRY BOOK!
What is Radiation that is not a particle?
Radiation will always remain a particle so long as it doesn't come in contact with MOST direct sunlight, or water. In that case, water becomes irradiated and the Particle becomes part of the water..answer 2 electromagnetic radiation - radio waves do not involve particles. Sound waves, heat, and UV light etc also are radiation. 'Radiation' is also used in biology, to describe the spread .

How is thermal energy transferred from particle to particle?
Thermal energy is transferred from particle to particle through three main mechanisms: conduction, convection, and radiation. In conduction, heat is transferred through direct contact between particles. In convection, heat is transferred through the movement of fluids. In radiation, heat is transferred through electromagnetic waves.
