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.
Is zero degrees celsius the coldest possible temperature?
No, zero degrees Celsius is not the coldest possible temperature. Absolute zero, which is equivalent to -273.15 degrees Celsius, is the lowest possible temperature where all molecular activity ceases.
What is absolute zero Celsius?
Absolute zero Celsius is the lowest temperature possible on the Celsius scale, at which point particles have minimal energy and movement ceases. It is equivalent to -273.15 degrees Celsius.
Can scientists cool matter to absolute zero?
No, reaching absolute zero (0 Kelvin) is theoretically impossible because it would require a complete absence of thermal energy. Scientists can get very close to absolute zero using various methods, such as laser cooling and magnetic cooling, but they cannot achieve absolute zero.
What is absolute zero what is the temperature of absolute zero on the kelvin and Celsius scale?
Absolute zero is the lowest temperature that is theoretically possible, at which the kinetic energy of particles is minimal. It is 0 Kelvin (K) and -273.15 degrees Celsius (°C).
Is it possible to achieve a temperature that is colder and absolute zero?
I think the term you're looking for is cryogenic processing. The NIST defines cryogenic temperatures as those below 93.2 Kelvin. Slowly reducing temperatures, to prevent damage from thermal shock, to below 93.2 Kelvin is a cryogenic process.
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.
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.
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.
Use absolute zero in a sentence?
Absolute zero is 0 K, or -273 degrees Celsius.
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.
Is zero degrees celsius the coldest possible temperature?
No, zero degrees Celsius is not the coldest possible temperature. Absolute zero, which is equivalent to -273.15 degrees Celsius, is the lowest possible temperature where all molecular activity ceases.
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.
