•Binding Energy(BE)- break ionic bonds @ lower temperatures •Coulomb force (satisfies 3 rd law) has an inverse square, radius goes up by 4,F=1/16 •K B T<BE:not a lot of moving add lots of E to separate ions, thermal •eminate outward for positive charges, inward for negative charges energy is small, stable, K B T>BE: a lot of moving, unstable, falls apart •electric field goes to zero as you move away from the charge •+charge PE highest near surface, −charge highest PE when potential V is low •↑velocity, ↑drag force (large fragments have a lower velocity) •more charge you move, the more work you have to do~voltage change •small fragments go farther because the drag force on them are smaller •polar:molecules do not overlap, so they have a permanent dipole moment •force between 2 charges *always b/t two things* •asymmetry of H 2 O dipole moment pointed toward more + H + atoms (− +) •bigger the charge, the bigger the force •polar nature of H 2 O allows it to dissolve charge molecules easily •external electric field separation of the – and + •↑K=↑induced electric field •strong external field ↓ temperature gives you a better alignment •tendency to align in the direction of the electric field •absence of external electric field, dipoles points in random direction •polar mol. create own electric field, induced field= random alignment

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
