what are the two requirements can matter exist at absolute zero
Absolute zero means that there is NO heat. Even an electron moving around its nucleus generates heat, although it is minimal.
The requirements you are seeking are for what? If you respond to this post with a more clearer question, we will do our best to help you,
I hope this helps. Thanks for asking.
sorry i meant thw two requirements of matter
No problem! The two requirements for matter to exist at absolute zero are:
1. Removal of all thermal energy: Absolute zero is defined as the temperature at which all thermal motion ceases. This means that the matter must have no residual heat or thermal energy. To achieve this, the matter must be isolated from any external heat sources and thermally insulated to prevent the transfer of heat.
2. Overcoming quantum effects: At low temperatures, quantum mechanical effects become significant and can prevent matter from reaching absolute zero. Particles, such as atoms or molecules, can undergo a phenomenon called Bose-Einstein condensation, which is a quantum phase transition. Bose-Einstein condensation occurs when a significant fraction of particles occupy the lowest energy state. This requires the particles to have a low density, interact weakly with each other, and have a high degree of confinement.
It is important to note that reaching absolute zero is not yet technically achievable, although scientists have been able to cool certain types of particles to extremely low temperatures, very close to absolute zero. Achieving absolute zero is an ongoing area of research in the field of cryogenics.
