It's false because the transfer of energy through matter by direct contact of its particles is conduction.
Have a nice day :)
False. The transfer of energy through empty space is called radiation. Convection is a circular flow that transfers heat in matter.
No. Heat transfer through empty space can only occur through radiation.
No. Convection is movement of liquid or gas caused by variation in density due to temperature differences.
false
true
False.
True
Convection, radiation, and conduction
both radiation and conduction give heat to another object.
Radiation
Carbon does not transfer via radiation. Carbon can only "conduct" in the sense that it can diffuse through a solid if the temperature is high enough. Carbon can convect in convective models, and the analyses of both heat transfer and mass transfer in solid surface - fluid mediums are *very* similar.
Depends on the material itself(for conduction) or it's surface and the temperature(for radiation) - at very high temperatures(like a lightbulb filament), radiation is far more significant then conduction, but a heatsink in a normal PC is doing to be far more dependant on conduction then radiation...

Convection, radiation, and conduction
There are three ways in which heat can be transferred from one surface to another. These three ways are conduction, convection and radiation.
Energy is transferred between the earths surface and the atmosphere via conduction, convection, and radiation. Conduction is the process by which heat energy is transmitted through contact with neighboring molecules.
