Consider N free particles wi which the energy of each particle can assume two and only two distinct values , O and E (E> o ) . Denote by no and me the number of particles with energy 0 and energy E (a) find the entropy of the system (b) find the most probable values of Mo and n, and their mean square fluctuation (c) find the temperature as a function of the total energy U and show that - it can be negative

1) a. water molecule breaks up into hydrogen and oxygen on passing electricity. does this involve breaking intermolecular or intramolecular forces of attraction. explain b. on boiling water changes to water vapor. does this involve breaking intermolecular or intramolecular forces of attraction. explain methanol evaporates faster than water. contrast the intermolecular forces and the vapor pressures of methanol and water?
