	Celsius temperature scale – FREE Celsius temperature scale Information \| Encyclopedia.com: Facts, Pictures, ...
		Celsius temperature scale, temperature scale according to which the temperature difference between the reference temperatures of the freezing and boiling points of water is divided into 100 degrees.
		Temperatures on the Celsius scale can be converted to equivalent temperatures on the Fahrenheit temperature scale by multiplying the Celsius temperature by 9/5 and adding 32° to the result, according to the formula 9 C /5+32= F.
		Absolute zero, or 0°K, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of -273.15° on the Celsius temperature scale.

	Temperature
		A convenient operational definition of temperature is that it is a measure of the average translational kinetic energy associated with the disordered microscopic motion of atoms and molecules.
		Temperature is not directly proportional to internal energy since temperature measures only the kinetic energy part of the internal energy, so two objects with the same temperature do not in general have the same internal energy (see water-metal example).
		Temperatures are measured in one of the three standard temperature scales (Celsius, Kelvin, and Fahrenheit).

	Temperature - encyclopedia article - Citizendium
		Temperature is a physical property of a system that underlies the common notions of "hot" and "cold", in which something that is hotter has the greater temperature.
		Temperature arises from the random microscopic motions of matter, where temperature is related to the average kinetic energy of these microscopic motions.
		Temperature is measured with thermometers that may be calibrated to a variety of temperature scales.

		The customary unit of temperature is the Centigrade degree, 1/100 of the difference between the temperature of melting ice and that of water boiling under standard atmospheric pressure.
		The fundamental temperature scale is the absolute, thermodynamic, or Kelvin scale in which the temperature measure is based on the average kinetic energy per molecule of a perfect gas.
		The zero of the Kelvin scale is -273.15 degrees C. The temperature scale adopted by the International Bureau of Weights and Measures is that of the constant volume hydrogen gas thermometer.

	Temperature
		One of the earliest temperature scales was that devised by the German physicist Gabriel Daniel Fahrenheit.
		In this scale, absolute zero is at -273.16° C, which is zero K, and the degree intervals are identical to those measured on the Celsius scale.
		The periodic temperature changes are due mainly to the sun's radiant heating of the land areas of the earth, which in turn convect heat to the overlying air.

	Temperature
		To ensure that the temperature of the surrounding air is the same as the thermometer, it must be shaded from sunlight and be exposed to adequate ventilation.
		The Celsius scale is fixed by two points, the freezing and boiling point of water, which at normal atmospheric pressure are 0°C and 100°C respectively.
		Absolute zero, the coldest temperature possible in the universe is 0K or -273°C. Because one Kelvin is equivalent to one degree Celsius, 0°C is the same as 273K.

	The International Temperature Scale 1990
		The International Temperature Scale 1990 ITS-90, replaced a long line of previous attempts throughout the twentieth century to regulate the measurements of matter-energy on an international level among different laboratories.
		As of 1990 the unit for measuring temperature in Absolute Temperature or on the Kelvin scale is the unit of the Kelvin, not the degree Kelvin.
		Although the International Practical Temperature Scale of 1968 (ITPS-68) had the unit of measurement as the degree Kelvin, since 1990 it is simply the Kelvin.

		The Kelvin temperature scale is an absolute scale having degrees the same size as those of the Celsius temperature scale; the Rankine temperature scale is an absolute scale having degrees the same size as those of the Fahrenheit temperature scale.
		The temperature 0 K is called absolute zero and corresponds to the point at which the molecules and atoms have the least possible thermal energy.
		In this scale a temperature difference of 1 degree is the same as a 1 K temperature difference, so the scale is essentially the same as the kelvin scale, but offset by the temperature at which water freezes (273.15 K).

	Temperature Scales
		Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts.
		Until the 1970s the Fahrenheit temperature scale was in general common use in English-speaking countries; the Celsius, or centigrade, scale was employed in most other countries and for scientific purposes worldwide.
		Celsius temperature scale also called centigrade temperature scale, is the scale based on 0 for the freezing point of water and 100 for the boiling point of water.

	Absolute zero Summary
		Absolute zero is the point on the thermodynamic (absolute) temperature scale where all kinetic motion in the particles comprising matter ceases and they are at complete rest in the “classic” (non-quantum mechanical) sense.
		At absolute zero, the molecules and atoms in a system are all in their ground state, the state of lowest possible energy, and a system has the least amount of kinetic energy allowed by the laws of physics.
		As mentioned, absolute or thermodynamic temperature is conventionally measured in Kelvins (Celsius-size degrees), and increasingly rarely in the Rankine scale (Fahrenheit-size degrees).

	Temperature - Kelvin Scale
		The Kelvin temperature scale (K) was developed by Lord Kelvin in the mid 1800s.
		At the freezing point of water, the temperature of the Kelvin scale reads 273 K. At the boiling point of water, it reads 373 K. Whereas the Kelvin scale is widely used by scientists, the Celsius or Fahrenheit scales are used in daily life.
		The zero point on this scale is base on the point at which the pressure of all dilute gases mathematically project to zero from the triple point of water (see graph at left).

		Absolute zero, or 0°K, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of -273.15° on the Celsius temperature scale.
		When writing temperatures in the Kelvin scale, it is the convention to omit the degree symbol and merely use the letter K. The temperature scale is named after the British mathematician and physicist William Thomson Kelvin, who proposed it in 1848.
		Another absolute temperature scale, the Rankine temperature scale, is used by some engineers.

	Thermodynamic temperature - Wikipedia, the free encyclopedia
		Thermodynamic temperature is the absolute measure of temperature and is one of the principal parameters of thermodynamics.
		Thermodynamic temperature is an “absolute” scale because it is the measure of the fundamental property underlying temperature: its null or zero point, absolute zero, is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance.
		In fact, his calculations projected that absolute zero was equivalent to −240 degrees on today’s Celsius scale—only 33.15 degrees short of the true value of −273.15 °C. Anders Celsius (1701 – 1744) created a “backwards” version of the modern Celsius temperature scale whereby zero represented the boiling point of water and 100 represented the melting point of ice.

	1/29/92 - What is absolute zero? (Site not responding. Last check: )
		On the Fahrenheit scale, water freezes at a temperature of 32º Fahrenheit and boils at 212º F. Absolute zero on this scale is not at 0º Fahrenheit, but rather at -459º Fahrenheit.
		On the Celsius scale, absolute zero corresponds to a temperature of -273º Celsius.
		On this scale, water freezes at 273 K and boils at 373 K. Only on the Kelvin temperature scale does absolute zero actually fall at 0 K. The accompanying diagram compares the three temperatures scales.
