Absolute zero is the theoretical temperature at which all substances have zero thermal energy. Originally conceived as the temperature at which an ideal gas at constant pressure would contract to zero volume, absolute zero is of great significance in thermodynamics and is used as the fixed point for absolute temperature scales. Absolute zero is equivalent to 0 degrees Kelvin, -459.67 degrees F, or -273.15 C.
The velocity of a substance's molecules determines its temperature; the faster the molecules move, the more volume they require, and the higher the temperature becomes. The lowest actual temperature ever reached was two-billionth of a degree above absolute zero. It was achieved by a team at the Low Temperature Laboratory in the Helsinki University of Technology, Finland, in October, 1989.
Having a limiting temperature has several thermodynamic consequences for example at 0 kelvin all molecular motion does not cease there is just no energy available for transference to other systems it is therefore more accurate to say that at absolute zero molecular energy is minimal if we say that all substances have zero energy this is a violation of the Heisenberg Uncertainty Principal so it is impossible to have zero energy.
The opposite of absolute zero is called Planck Temperature.
As of now it is the highest possible temperature that matter can exist at.
It is approximately 1.41679 x 10^32 Kelvin.
Beyond this temperature everything turns to energy, all subatomic particles break down and become individual black holes destroying space and time.
The universe has already reached this temperature once during the first instant of the Big Bang.
Absolute zero is the theoretical temperature at which all atomic motion stops. However, this temperature is unattainable, because it represents a complete lack of energy within particles of matter. Even in deep space, this temperature cannot be reached so, like the speed of light, it is a scientific limit which can only be approached. On the Kelvin scale it's 0, on the Celsius scale it's -273.16.
I think you might have wanted to tell us a little more information. It may be of use to know that absolute zero, 0 K = -273 C; the freezing point of water 0 C =273 K, and the boiling point of water, 100 C = 373 K
All molecular motion stop at cease at : (1) -459 degrees in FAHRENHEIT SCALE (2)-273 degrees in CENTIGRADE SCALE and on zero at kelvin scale. For more details ,contact at saqibahmad81@yahoo.com
The lowest possible temperature on the Celsius scale is -273.15 °C. This is the same as 0 K on the Kelvin scale, which is the SI base unit of thermodynamic temperature. This temperature is called absolute zero, because it is the point where all molecular motion stops.
In the Kelvin system 0 is set at he coldest possible temperature which is called absolute zero. Each degree kelvin is equal to a degree Celsius. The freezing point of water is 273.15 K so absolute zero is -273.15 deg C. There can be nothing colder than 0 K.
Yes, absolute zero is equal to -273°C. -273.15°C actually
-273 C
-273 C is absolute zero
absolute zero: -273'C
-273 deg C
-273.15 C to be exact.
The scale is called the Kelvin scale, where 0 Kelvin is equivalent to -273 degrees Celsius. It is an absolute temperature scale that starts at absolute zero, the theoretical absence of all thermal energy.
The Celsius temperature at absolute zero is -273.15 degrees Celsius. This is the point at which molecular motion theoretically ceases.
Objects at absolute zero, -273 degrees C.
Absolute zero is 0 Kelvin, or about -273 Centigrade.
The temperature -273°C is known as absolute zero. At this temperature, all molecular motion ceases, making it the lowest possible temperature on the Kelvin scale.
-273 degrees. This is called absolute zero or the point at which you cannot get any colder. It is theoretically impossible get colder than absolute zero.
