Question

In all states of matter, atoms of all elements
A.
are the same size.
B.
bind together the same way.
C.
are in constant motion.
D.
all of these

Answer 1

C or D, though I'm not positive which. Atoms are always in constant motion, but I'm not sure about the other options.

Answer 2

@unicorn_nips No, there is an absolute zero. This temp (absolute zero) is not defined in the same sense as our daily used C and F scales. Instead it is the point at which atomic motion stops, though it may be impossible to actually reach absolute zero.
