At 0 Kelvin (K), also known as absolute zero, the substance would be at its lowest possible temperature and have minimal thermal energy. Several changes would occur to the substance at this temperature:
1. All molecular motion would come to a complete stop. At absolute zero, all atoms and molecules in the substance would have no kinetic energy and would be in their lowest possible energy state.
2. The substance would become extremely brittle. As temperature decreases, materials tend to become more brittle. At absolute zero, the substance's lack of thermal energy would make it very fragile and prone to breaking or shattering easily.
3. Any residual thermal energy would be released as heat. If the substance is gradually cooled to 0 K, any remaining thermal energy would be released as heat until it reaches absolute zero.
4. Quantum effects may become prominent. At extremely low temperatures, quantum mechanical effects become more significant. These effects can include phenomena like superconductivity and Bose-Einstein condensation, where particles behave in unique ways due to their wave-like nature.
Overall, at 0 K, the substance would exhibit very different properties than at any higher temperature due to the absence of molecular motion and minimal thermal energy.
