Temperature
"Dress warm, kids. The temperature is only going to reach 20°F today." Your parents have probably said something like this to you many times. But what do they mean by the word temperature (tem-per-ah-chur)?
| |
Temperature is related to the amount of thermal energy or heat in a system. As more heat is added the temperature rises, similarly a decrease in temperature corresponds to a loss of heat from the system.
| |
Temperature gradients in the atmosphere are important in the atmospheric sciences ( meteorology, climatology and related fields). Contents ...
| |
The temperature of a black hole is determined by the ' black body radiation temperature' of the radiation which comes from it. (e.g., If something is hot enough to give off bright blue light, it is hotter than something that is merely a dim red hot.) ...
| |
Temperature is measured with thermometers that may be calibrated to a variety of temperature scales.
| |
temperaturethe degree of heat or cold in something (measured by a thermometer) ...
| |
antenna temperature In radio astronomy, a measure of the power absorbed by the antenna.
| |
Surface temperatures and seasons. Because of its proximity to the Sun, the surface of Mercury can become extremely hot. High temperatures at " noon" may reach 675 K, while the "predawn" lowest temperatures are 100 K.

Color and TemperatureClick on animation to play As you saw the in the previous Explore exercise, the temperature of an object determines the peak wavelength of its spectrum.
| |
Color and TemperatureA star's color can give clues to an important property of a star: its average temperature. All objects give off " thermal radiation" - light waves emitted from the random motions of atoms inside the object.
| |
The graph of temperatures on the earth over the last 160,000 or, even more so, 700 million years is a startling accomplishment.
| |
Temperature record The temperature record shows the fluctuations of the temperature of the atmosphere and the oceans through various spans of time. The most detailed information exists since 1850, when methodical thermometer-based records began.... .

Temperature Map of Ganymede This map shows the temperatures for most of the surface of Ganymede made from data taken by the Photopolarimeter/Radiometer (PPR) instrument on June 26, 1996 as Galileo approached the sunlit side of the moon.
| |
Temperature is a measure of the average heat or thermal energy of the molecules in a substance. The atoms and molecules in a substance do not always travel at the same speed.
| |
TEMPERATURETemperature is a measure of how hot or cold something is - how much heat energy it has. Temperature is essentially a measure of how fast the particles in a body are moving (or vibrating).
| |
Temperature Control Subsystems
An interplanetary spacecraft is routinely subjected to extremes in temperature.
| |
TEMPERATURE ON EARTHThe temperature on Earth ranges from between -127°F to 136°F (-88°C to 58°C; 185 K to 311 K). The coldest recorded temperature was on the continent of Antarctica (Vostok in July, 1983).
| |
Temperature, luminosity and chemical abundances The color is often used to determine the temperature of individual stars. Most stars have stellar spectra similar to that of a blackbody.
| |
Temperature is usually measured using either the scale introduced in 1714 by Farenheit or the one proposed in 1742 by Celsius.
| |
Temperature variations in leftover radiation from the Big Bang mark sites where the first galaxies probably formed (red, yellow).
| |
temperature A measure of the amount of heat in an object, and an indication of the speed of the particles that comprise it.
| |
Temperature and Density Determinations: All line ratios that are not fixed by atomic parameters are to some extent dependent on both temperature and electron density.
| |
TemperatureA measure of the average kinetic energy of the particles of a system. Scales ...
| |
temperature - (n.) A measure of heat intensity, or how energetic the particles of a sample are. terminator - (n.) ...
| |
TemperatureA measure of the amount of heat energy in a substance, such as air, a star, or the human body.
| |
A temperature scale on which the freezing point of water is 0° C and the boiling point is 100° C. Cenancestor An alternative term for the Last Common Ancestor of all life on Earth.
| |
A temperature scale with the same divisions as the Celsius (centigrade) scale and with the zero point at 0° absolute. (Room temperature is about 295 K). [H76] Kelvin scale ...
| |
The temperature in the Sun's center (the core) is about 27,000,000 (27 million) degrees Farenheit (about 15 million degrees Centigrade). The surface temperature is about 6,100 degrees Centigrade.
| |
Low temperatures are hard on equipment, vehicles, and people. Cameras malfunction, batteries go dead, and there's a risk of hypothermia and frostbite. Still, the prospect of a clear, winter night is tough to resist.
| |
The temperature of the radio telescope, its reflector, and its receiver are all sources of noise with which the observer must contend.
| |
High- temperature rock types, including laminated and welded blocks of sand, and "tektites", or glassy spatters of molten rock.
| |
With a temperature of 4995 Kelvin, the lesser of the two (Mu) shines with the light of just 45 Suns, not all that much for a giant, from which we derive a radius of 9 times that of the Sun, which agrees very well with a value of 8.
| |
Surface temperatures on Mercury range from about 90 to 700 K (-180 to 430°C, -292 to 806°F), with the sub solar point being the hottest and the bottoms of craters near the poles being the coldest.

Celsius: A temperature scale that assigns the value 0o C to the freezing point of water and the value of 100o C to the boiling point of water at standard pressure.
| |
The reason temperatures affect absorption lines is not too difficult to understand in a general way.
| |
Ionospheric temperatures The electron temperature responds readily to the auroral precipitation with a strong increase. Ion temperatures, on the other hand, are elevated mainly by frictional heating due to strong electric fields.
| |
The surface temperature on Venus is highly uniform and is about 459° C (732 K/858° F); the surface pressure is 96 bars (compared with 1 bar for earth); the atmosphere of the planet consists of nearly all carbon dioxide (CO2).
| |
Pluto's surface temperature varies ranges from -228 to -238 °C (-378 to -396 °F) during the course of its orbit, as the planet gets as close to the Sun as 30 AU before swinging as far away as 50 AU.
| |
When stars reach a temperature of 100,000,000 degrees c (180,000,000 degrees f), the helium ash itself begins to fuse, and the mechanism that once sustained the steady state of the stars becomes operational once again.
