What is the absolute temperature?

Answer 1

Absolute temperature is the temperature measured relative to the absolute zero.Absolute zero is the lowest possible temperature, occurring when no heat energy remains in a substance. Absolute zero is the point at which particles have a minimum energy, determined by quantum mechanical effects, which is called the zero-point energy. By international agreement, absolute zero is defined as precisely 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale, and -273.15°C on the Celsius scale.[Absolute zero is also precisely equivalent to 0 °R on the Rankine scale (also a thermodynamic temperature scale), and –459.67 °F on the Fahrenheit scale.

To establish an instrument to measure a range of temperatures, in 1593 Galileo Galilei invented a rudimentary water thermometer. One of the first to discuss the possibility of an “absolute cold” on such a scale was Robert Boyle who in his 1665 New Experiments and Observations touching Cold, stated the dispute which is the primum frigidum is very well known among naturalists, some contending for the earth, others for water, others for the air, and some of the moderns for nitre, but all seeming to agree that:

“ There is some body or other that is of its own nature supremely cold and by participation of which all other bodies obtain that quality.
The absolute temperature is obtained by adding 273.15to the temperature in degree celsius.

Answer 2

An absolute measure is based on a defined reference point, which is often zero, and the units of measure mark off fixed intervals. In the case of absolute temperature, whose fixed interval units of measure are called degrees Kelvin, the reference point is in fact zero degrees Kelvin. There was reason for selecting 0 degrees Kelvin as the reference point. That's the point where, theoretically, all molecular motion ceases and, as you know, we call that point "absolute zero." You gave 300 Nivlek as an absolute temperature; so it's not clear what you mean when you ask "How can I establish absolute temperature...?" Seems to me, you've already done that with the 300 Nivlek. I presume, going along with this, 1 Nivlek = -1 Kelvin degree. So in the real world, your Gallium triple point (solid, liquid, gas) would be - 300 Kelvin, which is impossible unless you change the laws of physics by sliding into a parallel universe where the laws we know do not apply. May the force be with you.

Answer 3

The very first answer by "rhsaunde…" and the other by "Rob" both have correct answers, and all other answers that say the same as these two are correct.

Rob's answer also explains the relationship between the two most used temperature scales.

Scientist use more coorect version and engineers use an approximation.

So the approximate value of Asolute zero= 0= -273 degrees C= -460 degree F, all molecular activity stop at these temperature, we have not reach this temperature in the laboratory yet, but we are very close to it, last I saw an artical and if my memories are not failing me, we have reach -453 degrees F, in a lab at south pole. It would be interesting to remotely examine a hydrogen molecuel at even this temperature for the understanding of molecuelar activity.

Make sure you make note of negetive sign, some of the answers have correct modular value but they are wrong without proper sign.

The electrons moving randomly in a single atom shoud also stop at -273.xxxx and -459.xxxx (absolute zero).

Answer 4

It is the temperature on the Kelvin Scale.

0 kelvin is the temperature at which there is no heat energy left in a substance. This is also called Absolute zero.

0 Kelvin is aproximately -273 Celsius.

So if it were 0 degrees Celsius out, it would be 273 degrees Kelvin. The absolute temperature would be 273 degrees.

Answer 5

It is the theoretical temperature at which gases contract to zero with temperature. It is also the temperature at which all kenetic movement stops. In fact, all gases become liquid before reaching that point, so the gas law is theory. Using various methods, it has been possible to get a tiny fraction of a degree of absolute zero. It isn't easy.

Answer 6

Absolute zero is the theoretical point where all molecular movement stops. Absolute zero is called Kelvin 1. Kelvin scale uses Celsius increments.

Answer 7

Absolute temperature is measured in degrees Kelvin or degrees Rankine.

Degrees K = Degrees C + 273.16

Degrees Rankine = Degrees F + 459.67

Answer 8

Temperature taken in Kelvin scale.

Answer 9

0 Kelvin=-273 degree C

Answer 10

the absolute temperature is 0 . if my question is wrong than you give me 100 no.
