Question
In summer 2023, scientists scrambled to replicate a non-peer-reviewed arXiv [archive] paper claiming that this compound could function as a room temperature superconductor. For 10 points each:
[10h] Name this lead apatite which two namesake South Korean scientists theorized could levitate due to the introduction of copper atoms.
ANSWER: LK-99 [or Lee-Kim 1999]
[10m] Lee and Kim originally believed that their material exhibited this superconductor property in which external magnetic fields are expelled, thus causing levitation in magnets.
ANSWER: Meissner effect [or the Meissner-Ochsenfeld effect]
[10e] Several experiments contradicted the claim that LK-99 was a room-temperature superconductor by measuring a high value of this quantity. This quantity equals voltage over current according to Ohm’s law.
ANSWER: resistance
