ACS Domain 4: States of matter or solutions Welcome to your ACS Domain 4: States of matter or solutions 1. ACS: States of matter or solutions Which property is NOT characteristic of gases compared to liquids and solids? Indefinite shape Indefinite volume Low compressibility High expansibility None 2. ACS: States of matter or solutions What will increase the solubility of a gas in a liquid? Increasing the temperature Decreasing the temperature Decreasing the pressure above the solution Adding a nonpolar solute None 3. ACS: States of matter or solutions Which factor does NOT affect the rate of dissolution of a solute in a solvent? Temperature of the solvent Surface area of the solute Agitation of the solution Color of the solute None 4. ACS: States of matter or solutions Raoult's Law applies to which type of solutions? Non-ideal solutions Ideal solutions Solutions with volatile solutes only Electrolytic solutions None 5. ACS: States of matter or solutions What is the effect of adding a non-volatile solute to a solvent on the boiling point of the solvent? It decreases the boiling point. It increases the boiling point. It does not change the boiling point. It decreases then increases the boiling point. None 6. ACS: States of matter or solutions In terms of molecular movement, how do gases differ from liquids? Molecules in gases move slower than in liquids. Molecules in gases are more closely packed than in liquids. Molecules in gases move faster and are further apart than in liquids. There is no significant difference in molecular movement. None 7. ACS: States of matter or solutions What is true about the vapor pressure of a solution containing a non-volatile solute? It is higher than the vapor pressure of the pure solvent. It is lower than the vapor pressure of the pure solvent. It is equal to the vapor pressure of the pure solvent. Vapor pressure is independent of the presence of a non-volatile solute. None 8. ACS: States of matter or solutions What describes the critical point on a phase diagram? The temperature and pressure above which a liquid can no longer exist. The lowest temperature at which a substance can exist in liquid form. The condition under which all three phases exist in equilibrium. The maximum density point for any substance. None 9. ACS: States of matter or solutions Which factor does NOT affect the rate of dissolution of a solute in a solvent? Temperature of the solvent Surface area of the solute Agitation of the solution Color of the solute None 10. ACS: States of matter or solutions In terms of molecular movement, how do gases differ from liquids? Molecules in gases move slower than in liquids.
