Explain why dissolving a nonvolatile solute in water affects the system in the following ways by selecting all true statements: Incorrect. The system has a higher boiling point than water. O The solute lowers the vapor pressure of the water. O The solute increases the vapor pressure of the water. O A higher temperature is required to obtain a vapor pressure of water equal to 1 atm. O A lower temperature is required to obtain a vapor pressure of water equal to 1 atm. O The normal boiling point is the temperature at which the vapor pressure is 1 atm. Hint Incorrect. The system has a lower freezing point than water. O Presence of the solute lowers the triple point. O Presence of the solute increases the triple point. O For all substances, the change in the triple point results in a lower freezing point. O For water, the change in the triple point results in a lower freezing point. O None of these. Hint
