and the molecules in the water move slower (decreasing temperature). When fast-moving atoms or molecules hit slower-moving atoms or molecules and increase their speed, heat is transferred. This ...

Radiation is the transfer of heat energy from a region of high temperature to a region of low temperature by infrared radiation. Unlike conduction and convection, radiation takes place without the ...

When infrared radiation is absorbed by an object it is heated and its temperature rises ... radiators actually transfer most of their heat to a room by convection, not radiation.
