Is ionization energy always a positive or negative value?  Explain why in just a few words. (WCSU24)

(WCSU24) Select the appropriate word that makes each sentence true. a. Melting is . b. Intermolecular forces occur molecules.  c. When intermolecular interactions are broken, energy is .   d. The energy absorbed when liquid water vaporizes is than the energy absorbed when ice (solid water) melts.  e.   A temperature decrease is observed when NH4Cl is dissolved in water.  We can conclude that the total intermolecular interactions formed between solute and solvent are than those broken.  f. As temperature of a substance increases, kinetic energy . g. The
