At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale.

What happens to a gas at 0k?
Theoretically, at absolute zero the volume of an ideal gas would be zero and all molecular motion would cease. In actuality, all gases condense to solids or liquids well above this point.
Has 0k been reached?
Nothing in the universe — or in a lab — has ever reached absolute zero as far as we know. But we do now have a precise number for it: -459.67 Fahrenheit, or -273.15 degrees Celsius, both of which equal 0 kelvin. Different materials vary in how cold they can get, and theory suggests well never get to absolute zero.
What happens to water at zero kelvin?
At such temperatures, water begins to freeze. Absolute zero is the lowest possible temperature, which is reached at zero kelvin. To model how cold absolute zero is, think about this: Water freezes at 0 °C or 32 °F), which is 273 kelvins (not even close to absolute zero).
What happens when a gas is cooled?
If a gas is cooled, its particles will eventually stop moving about so fast and form a liquid. This is called condensation and occurs at the same temperature as boiling. Hence, the boiling point and condensation point of a substance are the same temperature.
Does the type of gas affect zero temperature?
It appeared that an “ideal gas” at constant pressure would reach zero volume at what is now called the absolute zero of temperature. Any real gas actually condenses to a liquid or a solid at some temperature higher than absolute zero. Therefore, the ideal gas law is only an approximation to real gas behaviour.
Why is 0k impossible?
Theres a catch, though: absolute zero is impossible to reach. The reason has to do with the amount of work necessary to remove heat from a substance, which increases substantially the colder you try to go. To reach zero kelvins, you would require an infinite amount of work.
What happens when a gas is cooled short answer?
Answer: When a gas is cooled ,its molecules becomes less active. They stay together not moving much. When cooled enough ,the gas becomes a liquid.
What happens to matter when it is cooled?
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.
At what temperature volume of gas is zero?
This point, with a temperature of –273.15 ˚C, is the theoretical point where the samples would have “zero volume”. This temperature, -273.15 ˚C, is called absolute zero.
What is the hottest day ever on Earth?
On September 13, 1922, a temperature of 136°F was recorded at El Azizia, Libya. This was eventually certified by the World Meteorological Organization as the hottest air temperature ever recorded on Earth.
What is the most coldest thing in the universe?
protoplanetary Boomerang Nebula The protoplanetary Boomerang Nebula, located 5,000 light-years from Earth, holds the record for coldest known object in the Universe. Outflows of gas, streaming out from the central dying star, reach temperatures below -270 degrees Celsius.
