11.   Imagine living in a house with walls that radiated heat without electricity or gas furnaces.

12.   It sits at the bottom of an included woven wicker basket and radiates enough heat to keep bread warm at the table.

13.   Just like the filament of a light bulb, the human body radiates heat, which can be detected as infrared radiation, or infrared light.

14.   On a clear, calm night with light winds the air at the ground cools rapidly as it radiates heat to space.

15.   Q. Where can I find the metal fins designed to fit over heating pipes, to allow the pipes to radiate heat into the room?

16.   Such conditions allow the ground to cool by efficiently radiating heat into space.

17.   The hot water circulates through pipes to radiators or heating panels that radiate the heat into the rooms.

18.   Resting on top of the doughnut hole was a metal card that radiated heat.

19.   The gas prevents the Earth from radiating heat back to space and also depletes its protective ozone layer.
