Simple answer: -273.15 degrees celcius.
Less simple answer: Absolute zero IS the temperature. Temperature is the average speed of the particles in a substance. The term "Absolute Zero" means that the speed of every single particle in a mass is absolutely zero; none of the particles are moving. If a single particle moves within the given mass, the average must be more than zero, and, consequently, the mass has not achieved Absolute Zero. There is no known way to bring a mass on Earth to Absolute Zero. It would take an infinite amount of energy to get to there.
Absolute zero is the lowest possible temperature where particles have minimal motion. If you were to touch an object at absolute zero, the extreme cold would cause rapid heat transfer from your body to the object, potentially leading to frostbite or severe tissue damage. However, achieving absolute zero is currently impossible in practice.
As an object approaches absolute zero, its atoms and molecules lose kinetic energy and slow down, but they will never completely stop moving due to Heisenberg's uncertainty principle. This principle states that it is impossible to precisely know both the position and momentum of a particle, preventing an object from reaching absolute zero.
This scenario is considered a paradox, as an irresistible force cannot exist alongside an immovable object in classical physics. It raises questions about the nature of the concept of an immovable object and an irresistible force.
An object would radiate the least amount of electromagnetic energy at absolute zero temperature, which is 0 Kelvin (-273.15 degrees Celsius). At this temperature, the object would have minimal thermal motion and therefore emit minimal radiation.
If an object has no atoms, it means it does not exist in a physical form. Atoms are the building blocks of matter, so without them, there would be no material substance or structure to the object. Essentially, it would be a non-existent entity.
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.
It is absolute zero and all molecular motion stops
they would die
It is not correct because the verb "reached" requires an object. As such, it should be phrased "You would have reached it two months ago" or, in place of the it, you can use any other noun or pronoun as an object.
nothing would happen
When observing an object, you can determine if it is not at absolute zero by looking for any signs of movement, such as vibrations or changes in temperature. Objects at absolute zero would not exhibit any movement or show any signs of heat.
How bright the object would be if it was the same distance from Earth as the sun is
You would be vaporised long before you actually reached the sun.
The object would behave as a part of fluid and it will remain where it is kept.
The object would float in a given liquid.
then they would play there
There's no fundamental reason that it should.
