When does absolute zero occur?
Absolute zero is the theoretically coldest temperature. It is not possible to actually achieve absolute zero, only to approach it. In laboratory experiments, temperatures below one microkelvin have been achieved - i.e., less than a millionth of a degree above absolute zero.
How cold -273 Celsius?
Absolute zero, the coldest possible.
Is zero degrees celsius the coldest possible temperature?
No, zero Kelvin is. 0K = -273.15°C. Known as absolute zero.
How is absolute zero and 0 k the same?
The Kelvin temperature scale is designed so that zero Kelvin is the lowest possible temperature, at which all molecular motion has ceased, hence, it is absolute zero.
What is the temperature called at which no more energy can be removed form matter?
I guess you mean, no more thermal energy (heat). That's the lowest possible temperature, called "absolute zero", or zero Kelvin.

What is absulte 0?
"Absolute Zero" refers to zero on the kelvin scale for temperature. Absolute Zero, or 0 kelvin ( = -459.67 degrees Fahrenheit = -273.15 degrees Celsius), is the coldest possible temperature. It is probably impossible to achieve this temperature, but you can get very close.
Is it possible for an object to have zero velocity?
Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.
Why it is not possible to cool a liquid to absolute zero?
Because - anything cooled to absolute zero would no longer be liquid.
What abslute zero is zero?
I will assume you meant to ask, "What is absolute zero?" Absolute zero is the lowest possible temperature, at -273 degrees Celsius, or 0 Kelvins.
Do molecules disappear at absolute zero?
No. They are as frozen still as they can ever be. It is said to be scientifically impossible to actually reach absolute zero.
What is coldest possible temperature called?
Absolute zero.
What is absolute zero and why is it impossible to achieve it?
Absolute zero is the lowest possible temperature. Basically, the closer you get to absolute zero, the harder it becomes to get even closer. However, it is possible to get very, very close - temperatures of less than a microkelvin, i.e., a millionth of a degree above absolute zero, have already been achieved.
Why is absolute zero only an idea and not something that exist in natural?
it is not possible to achieve this temperature because there is nothing as cold absolute zero with which to remove thermal energy with(it would actually need to be colder), they have come very close with laser cooling another problem is that at absolute zero all molecular motion stops, introducing a measuring device would add energy to the system causing it to move and thus leave absolute zero.
What is the difference between kelvin and absolute kelvin?
Kelvin is the absolute temperature - a temperature where absolute zero, the lowest temperature possible, is defined as zero. Therefore, in the phrase "absolute Kelvin", the word "absolute" seems redundant.
Is it possible to reach a temperature lower than absolute zero?
no
How cold -273 Celsius?
Absolute zero, the coldest possible.
