Re: States of matter and forces

It's easier to think of the states in relation to how densely packed the atoms are. Solids have atoms that are densely packed and have strong attractions. Thus, they will have stronger bonds.

Winter quarter scheduling

Hi everyone! As I'm trying to plan out my classes for the next quarter, I am finding it difficult to decide between taking both Chem14B and Chem14BL. Do you think it is a good idea to take the simultaneously?
