As temperature increases, what happens to density?
decreases (the molecules spread apart)
Water is weird! Water is most dense around what temperature and phase?
4 degrees Celsius (as a liquid) (on the esrt)
As temperature decreases,what happens to density?
density increases (the molecules move closer together).
As pressure increases, what happens to density?
density increases (the molecules move closer together).
If you break an object into smaller pieces, what happens to density?
the density stays the same.
As pressure decreases, what happens to density?
density decreases (the molecules spread apart).
