When fast-moving atoms or molecules hit slower-moving atoms or molecules and increase their speed, heat is transferred. This process is called conduction. The atoms in the hot spoon are moving faster ...

Trapped air prevents heat loss by conduction and convection. Radiation is the transfer of heat energy from a region of high temperature to a region of low temperature by infrared radiation.

Researchers have shown for the first time that heat transfer in the form of infrared radiation can influence chemical reactions more strongly than traditional convection and conduction methods.

In this video we'll take a look at thermal radiation, one of the three modes of heat transfer along with conduction and ...

In a joint experimental-theoretical work, a team of researchers, including theorists from UC San Diego, have shown for the first time that heat ...
