"Which statement applies to boiling but not to evaporation?" 1. The problem statement, all variables and given/known data Which statement applies to the boiling but not to the evaporation of a liquid? A The separation of the molecules increases greatly B At normal atmospheric pressure, the process occurs at one temperature only. C Energy must be provided for the process to happen. D All the bonds between molecules in the liquid are broken. 2. Relevant equations None. 3. The attempt at a solution I don't know, but to me B C D are all correct. A is incorrect because: Boiling-Yes, Evaporation-Yes B is correct because: Boiling-Yes, Evaporation-No (because occurs at all temperature) C is correct because Boiling-Yes (supply heat to boil), Evaporation: No (Molecules with higher kinetic energies will just escape, no need to supply any energies to them) D is correct because: Boiling-Yes (boiling occurs throughout the whole liquid, so all bonds broken), Evaporation-No (because I think that since only the fastest molecules escape, so it should not be "ALL bonds are broken".) Can someone teach me about this? Thank you.
