I'm helping my son with a science project and cant't seem
to find the research I need. I understand that all liquids have a
different freezing point, but what causes that? Does it have something
to do with the rate at which they crystalize. Are there some liquids,
like butter, and honey that never freeze? How does plasma play into
this? Help! Thanks!
All liquids have a different freezing point because all
are made of different kinds of atoms or molecules,
each of which has different interatomic (or intermolecular)
forces and different atomic (or molecular) sizes. These
two issues work together in a complex way to determine the
melting point. However, the rate of freezing is not generally related
to the value of the freezing point. That again is a complex
function of the detailed nature of the interatomic/intermolecular
forces and size, but depending on the substance forces might be
more important than size to determining one property or the other.
Butter and honey both freeze. You just have to get them cold enough.
I'm not sure what you mean by "plasma." Plasmas can only exist
at ultrahigh temperatures, like in plasma welding torches,
fusion reactors, or in stars. I'm not sure what that has to do with
Sorry, hope this was a little helpful.
