Document Summary

If it is going to come together, it will at low temp as a solid. Some molecules are attracted more than others. Van der waals forces and ldf - the real force comes from the molecules sharing electrons. Molecules want to come together but temp fights them. Average te of a molecule = temp. How much energy needed to break bonds that holds together as solid then liquid. Solid > break bond > liquid> break bond>gas. Vibrations, rotations, stretching bending > electrons are flying around. This is the heat capacity. (cp) internal energy inside molecule. How much energy do i need to break intermolecular bond that keeps things as solid > that energy converted to temp is the amount. Ice is different than water and water is different then steam. Molecules are working together at different level of intensity. Look at speed of all molecules > translated into distribution of energies > boltzmann distribution .
