Thermograms of heating a saucepan with water on an electrical stove. In this series water was heated from room temperature and brought to boiling in about 4 minutes. Thermography is a technique for visualizing the temperature of objects by recording the thermal emission at infrared wavelengths. This video was acquired with a specialized camera that is sensitive to electromagnetic radiation in the wavelength range of 8 to 14 micron. The camera produces 320x240-pixel frames where different colors correspond to different temperatures.
