Question

In the phase diagram on the left, what is the name for point Z on the diagram? Normal boiling point triple point critical point melting point zero point On the phase diagram at the left, which conversion results in sublimation of the substance? R to O x to O O to N M to O N to M Which ONE of the following is a correct statement of what happens when a nonvolatile solute is added to a pure liquid? The melting point and the boiling point of the liquid increase (higher temp.). The melting point and the boiling point of the liquid decrease (lower temp.). The melting point increases and the boiling point decreases. The melting point decreases and the boiling point increases. The melting point and the boiling point of the liquid do not change.

Explanation / Answer

7) C) critical point

8) E) sublimation occurs when solid converted to gas N to M

9)D) When a solute is added to a solvent, the vapor pressure of the solvent (above the resulting solution) is lower than the vapor pressure above the pure solvent.The boiling point decreases as the vapour pressure increases
