Question

How does this example show us how the strength of electrical
forces can be observed at a scale we can see with our eyes?
The NaCl molecules have such strong bonds with each other that do not
go into solution and this prevents H₂from forming bonds to become a
solid.
Electrical forces between H₂molecules are weakened by the NaCl,
which lowers the freezing point of the solution.
NaCl has a lower freezing point than H₂molecules do, so they remain
in their liquid phase for longer, preventing the solution from freezing.
Electrical forces between H₂molecules are strengthened by the NaCl,
which lowers the freezing point of the solution.
