It’s another day, and that means it’s time for another examination on an Advanced Placement subject! Today we’ll be looking at one of the cornerstones of scientific study; Chemistry! How much do you know about the states of matter, for example? Find out in this AP Chem Exam Review!
Very weak compared with kinetic energies of the molecules
Strong enough to hold molecules relatively close together
Strong enough to keep the molecules confined to vibrating about their fixed lattice points
Not strong enough to keep molecules from moving past each other
Strong enough to hold molecules relatively close together but not strong enough to keep molecules from moving past each other
More separated, more
More separated, less
Closer together, more
Closer together , less
Larger, greater
