Why the absence of motion is called absolute zero?
Absolute zero refers to the theoretical temperature at which particles have minimal energy, causing all motion to cease. It is considered the lowest possible temperature in the thermodynamic temperature scale and serves as a reference point for measuring temperature. At absolute zero, no heat can be lost from a system, making it impossible to reach this temperature in practice.
All molecular motion ceases at 0 Kelvin why?
All molecular motion stops at absolute zero because absolute zero is the coldest possible temperature. And it is only able to achieve this temperature if the molecules/atom do not possess any thermal energy. And thermal energy is what causes vibrating motion of the molecules/atom. Thus at this temperature no molecules/atoms will vibrate due to the complete lack of energy.
What temperature is absolute zero in degrees K?
Kelvin (K) is actually the same scale as Celsius (C), but whereas Celsius is set such that zero Celsius is the freezing point of water, the Kelvin scale is set such that zero Kelvin is absolute zero, which is the temperature at which all kinetic. Absolute zero is zero degrees Kelvin, at which point there is no kinetic activity in a molecule or atom. There are presently no theoretical means of achieving absolute zero.
What is the maximum wavelength of light in nm required to ionize a single rubidium atom?
The ionization energy of a rubidium atom is about 403 nm. Therefore, the maximum wavelength of light required to ionize a single rubidium atom would be higher than 403 nm.
When would water molceles stop moving?
Theoretically, the only way to completely stop the movement of any atom or molecule is to reduce its temperature to absolute zero.
What does the wavelength of electron if it moves with the speed of light?
-- First of all, since the electron has rest mass, it can never move at the speedof light.-- Following DeBroglie, the electron's wavelength is such that an integral numberof them fit around the length of the electron's orbit when it's bound to an atom.
Why is there no temperature lower than 0 K?
Because that is 'absolute zero' it is the temperate where atom get so cold they stop moving.
Does absolute zero really exist?
no, absolute zero is only a myth. Temperature is the measurement of thermal energy caused by the movement of the atoms. at absolute zero, atom freezes and it would be impossible to measure its temperature.
What would happen to an atom if it reached absolute zero?
There is nothing "magic" about absolute zero. It's unattainable in practice, but theoretically nothing in particular would "happen" if an atom did achieve that temperature. If you were hoping for an answer like "the electrons would stop moving and collapse into the nucleus", no, sorry, that's not going to happen.

What is the wavelength of gamma ray?
The wavelength of a gamma-ray is 10-11 metres

Can you able to achieve hypothetical temperature?
Scientist can achieve almost hypothetical absolute zero using laser cooling trapping atom motion. The lowest temperature achieve is now approximately 0.00015 K. For absolute 0 K without any digit, it would be a very challenging task that may never be achieve.
Does the half life change as a radioactive atom approaches absolute zero?
While the half-life can be affected by changes in the motion of atoms due to changes in temperature, the effect is negligible. Half-life is far more drastically affected by forces between particles within the nucleus rather than any atomic motion or atomic interactions. There may be a small decrease in decay rate as temperature decreases but it is negligible thus far. It has been proven that increases in decay rate with temperature are essentially zero. According to the current standard model of particle interactions the effects of temperature change on decay rate can be ignored at all temperatures.
Why it is not possible to find the absolute mass of an atom?
It is the smallest particle
