What is the transfer of heat through a material by the collision of particles?
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
True or false the transfer of energy through matter by direct contact of its particles is convection?
your ear hears sounds through a wall because of basic physics. when a noise is made, the air particles move. the particles then transfer the engery they received onto another particle. this process continues till you can hear the sound (till the particles reach your ear) you can hear though a wall because the particles in the wall absorb the motion and transfer that motion onto other particles passing the sound through.
Heat energy can be transfered through a conductor or medium, in three ways. Radiation, which is how the sun transfers energy, through waves. Convection, which is how wind works, the transfer of heat by mixing particles together. Conduction, which is how your hand warms up when someone touches it. The particles transfer their heat energy to adjacent particles.
Radiation is the mode of transfer of heat which does not require particles. Even through vacuum heat radiation can pass through. It is passed in the form of electromagnetic radiations. Heat radiations otherwise known as infrared radiations. It means that it is beyond the red end of the visible radiations named as VIBGYOR.
Either conduction, convection, or radiation. Conduction is when the two (or more) objects transfer heat through physical contact (this is how your stove works to heat a pot). Convection is the transfer of heat through liquid or gas by moving heated particles (this is how your oven works). Radiation is when heat is transfered through waves or particles (this is how the sun heats the earth).
Thermal conduction is the transfer of heat energy through direct contact. Heat energy is technically the kinetic energy of individual particles. The higher the kinetic energy, the more heat energy it contains. In thermal conduction, the particle with the higher kinetic energy loses some of that energy upon collision with a particle with lower kinetic energy. The second particle's kinetic energy is then increased, and upon collision with another particle it transfers some of its…
