Question

Is it possible to achieve zero kelvin in real life?

Answer 1

Not Possible,
Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures.” but it is still in practice

Atoms stop moving at this temperature and hence it is the coldest temperature

This theoretical temperature is determined by extrapolating the ideal gas law.

Absolute zero is taken as -273.15 °C or 0 kelvin.

It is still not physically possible to reach this temperature.
