Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points The theory used to explain the behavior of solids, liquids and gases is 1. the VSEPR theory. 2. the kinetic-molecular theory. 3. the atomic theory. 4. the molecular theory. 002 10.0 points Which one of the following statements does NOT describe the general properties of liq- uids accurately? 1. A liquid sample has a characteristic volume that does not change greatly with changes in pressure. 2. The liquid state is highly disordered com- pared to the solid state. 3. Liquids diffuse only very slowly when compared to solids. 4. A liquid sample has a characteristic volume that does not change greatly with changes in temperature, assuming that the liquid is not vaporized. 5. Liquids have high densities compared to gases. 003 10.0 points Consider the two water molecules O b b b b H H O b b b b H H → A → B Which statement is correct? 1.
