What is the transfer of heat by the direct contact of particles of matter called?

Answer 1

It depends on the type of heat transfer.for conduction:when thermal energy is applied to a material,the atoms and/or molecules of the material that are in direct contact with the heat source gain an increase in kinetic energy,as the thermal energy is transformed to kinetic energy.these atoms and/or molecules of the material then vibrate and move around faster than before, thus colliding with other atoms and/or molecules through elastic collisions.a chain reaction then occurs throughout the material,using this mechanism.as more and more atoms and/or molecules gain kinetic energy and collide with each other,this increases the material's temperature.keep in mind that this mechanism applies to conduction and convection,not for radiation(eg.you don't have to touch the sun in order for it to warm you up).I'm not sure about evaporation(eg. when you sweat and heat from your body is transferred to the surface of your skin and the air around it).hope this helps,even if its by a teenie tiny bit.

Answer 2

convection. No, convection is the movement of heat through a fluid (air or water, for example).

Answer 3

The transfer of thermal energy is heat. Heat is the transfer not the property. The thermal energy of any matter is the average kinetic energy of the molecules or atoms.

Answer 4

Conduction.
