Penguins,thermogram. A thermogram shows variation in temperature on the surface of an object,measured by the long-wave infrared radiation it emits. The temperature scale is colour-coded and runs from black (5.7 degrees Celsius,coldest) through blue,purple,pink and orange to yellow (warmest,29.9 degrees Celsisus). Penguin feathers trap a layer of air which helps to insulate the bird | |
