3. Another friend from chem class has a mother who is a chemist. Your friend's mother invites the class to
visit her lab and observe one of her experiments. In
her experiment, she super-cools a
pure sample of atoms to such a low
temperature (almost absolute zero)
that the atoms form a "super-atom"
where all of the particles exist in
the same energetic state at once!
What's really cool is when light
travels through this sample, it even
slows down! What is the sample's state?
