a) It ensures efficient energy transfer.
b) It prevents unwanted chemical reactions.
c) It minimizes molecular motion.
d) It maximizes electrical conductivity.

Answer 1

Cryogenics has to happen at -196°C to minimize molecular motion and prevent unwanted chemical reactions.

Step-by-step explanation:

The reason cryogenics has to happen at -196°C is to minimize molecular motion. At this extremely low temperature, the molecules have very little thermal energy and move very slowly. This is important because cryogenics involves freezing substances to extremely low temperatures to preserve them or achieve certain physical properties. By minimizing molecular motion, cryogenics can prevent unwanted chemical reactions and preserve the integrity of the materials being frozen.
