Absolute Zero?

Question

You know how Absolute Zero exsits. Then there would have to be something for heat right? With out something for heat, Absolute Zero Couldn't Exist.

Answer 1

? The question is poorly phrased.

Absolute zero is basically a theoretical concept that exists when the particles of a substance have no kinetic energy, which you would normally measure as temperature with a thermometer, for example, because of the number and strenght of collisions with the thermometer per second. At absolute zero, the particles are not moving, so there are no collisions and hence no recorded temperature.

Heat is a form of energy, in the infrared region of the spectrum, and should not be confused with temperature. As mentioned above, temperature is proportional to the kinetic energy of the average molecule, energy is supplied in the form of heat to raise this kinetic energy and hence the recorded temperature.

Hope this answers the question!

Answer 2

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.

While scientists cannot fully achieve a state of “zero” heat energy in a substance, they have made great advancements in achieving temperatures ever closer to absolute zero (where matter exhibits odd quantum effects). In 1994, the NIST achieved a record cold temperature of 700 nK (billionths of a kelvin). In 2003, researchers at MIT eclipsed this with a new record of 450 pK (0.45 nK).

Answer 3

no absolute zero cannot exist. they have come very close to it but couldnt reach. its means that no heat energy remains in a substance. Absolute zero is the point at which molecules do not move. In September 2003, MIT announced a record cold temperature .00000000045 K in a Bose-Einstein condensate of sodium atoms. they have a math formula and it states that zero can never be achieved, but we can get infinitely close

Answer 4

I don't know what you mean, but absolute zero is 0 degrees Kelvin. Which is -273 degrees celsius. Absolute zero cannot exist though. They've come close, but they never achieved it. Anyways, there is no such thing as cold. Cold is what we call when there "seems" that no heat is present. Heat is everywhere. Absolute zero is heat. In our eyes, it is cold, but it is actually heat.

Answer 5

Okay then. What's the question please? Any time there is movement between molecules, there is enough heat to allow the molecules to move. Absolute zero is the point in which there is no movement between molecules, because of the lack of sufficient heat. The movement between the molecules generates a small amount of heat, yet not enough to do significant damage to the whole structure of the compound(or element as the case may be) to allow it to self destruct.

Answer 6

Absolute Zero is 0 degrees Kelvin. That is the absolute lowest that temperature has ever been found in the universe. At that temperature, no life can exist, and basically, everything there dies and withers away. You couldnt even light a fire because the wood would cryogenically freeze.
