Lastly, as with kitchens, incandescent or LED bulbs in the 2,700 to 3,200 degrees Kelvin
range are the ideal choice for bathrooms, Molinelli says.
For example, in the MAX6576 you can scale the period to represent 10xT, 40xT, 160xT, or 640xT, where T is the temperature in degrees Kelvin
. Table 1 includes five of these single-wire-output devices in the total of 14 analog sensors because their output is continuously variable.
This enables the use of a standard low temperature fridge to cool the magnet to the required 4 degrees Kelvin
(minus 269 degrees C).
These magnets, which operate at temperatures at or above 20 degrees Kelvin
(as opposed to conventional superconducting magnets that operate at around 4 degrees Kelvin
) result in sharply reduced refrigeration costs that, in a fusion power plant, also would tend to lower the cost of electricity.
At the risk of getting too technical, the color temperature of light is measured in degrees Kelvin
. It's counter-intuitive, but "warm'' light sources are actually at lower temperatures on the Kelvin scale, and "cool'' light sources reside higher on the scale.
The researchers were able to take the temperature of the gas in the nebula by seeing how it absorbed the cosmic microwave background radiation, which has a very uniform temperature of 2.8 degrees Kelvin
(minus 455 degrees Fahrenheit).
The 131 wavelength of light is used for observing solar material heated to 10 million degrees Kelvin
, as in a solar flare.
While Nasa admits there is no scientific value to the video processing, it has resulted in a beautiful new view of the sun, bubbling with plasma at around 600,000 degrees Kelvin
For example, given that different metrologic systems are in use for the measurement of human body temperature, this parameter can be expressed in degrees Celsius (Europe), degrees Fahrenheit (US), or degrees Kelvin
"The helium burning sets in when the temperature in the contracting core reaches about 80 million degrees Kelvin
. The energy released can only raise the temperature further, as the high pressure on the degenerate matter prevents its expansion.
Fluorescent lighting at 3,500 degrees Kelvin
enhances skin tones.
"The difference is that these waves are being created in a gas cloud which is only 10-20 degrees Kelvin
above absolute zero (250 degrees below 0C).
Because of his experiments, his fellow scientists decided to measure color "temperatures" in his name; the higher the value of the light in degrees Kelvin
, the closer it is to sunlight.
Top right: An active region of the sun on a quiet day: gas at a million degrees Kelvin
is being ejected from the solar surface where the dark structures are only about 10,000 degrees.
Sunlight, the combination of all wavelengths of the visible spectrum, produces white light and has a color temperature of 4,000 to 5,000 degrees Kelvin
. Daylight, reflected sunlight, being bluer in color, is in the 5,500 to 6,500 degree Kelvin color temperature range.
