Heat usually follows a predictable path—spreading outward from a hot source until it dissipates evenly. But in some exotic ...

The human body is always regulating its temperature and can lower it in four different ways: vaporization, which it achieves by sweating radiation, which means releasing heat into the surrounding ...

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 ...

A method of cooling a liquid refrigerant after it has been boiled by heat from a heat source. Unlike the conventional cooling method, which uses a temperature difference to transfer heat from a heat ...

However, despite their name, radiators actually transfer most of their heat to a room by convection, not radiation. Normally radiant heaters must be at least red hot before they are effective.
