Question 2
adding more solute to a solvent
a)decreases its boiling point
b)does not affect its boiling point
c)increases its boiling point
d)increases its freezing point

C) Increases its boiling point

Explanation:

Adding more solute to a solvent increases its boiling point! This is a phenomenon described by the colligative properties. When we add a solvent to a solute, the boiling point increases.

Put in vapor pressure terms, a liquid boils at the temperature when its vapor pressure equals the surrounding pressure. For the solvent, the presence of the solute decreases its vapor pressure by dilution. Thus, a higher temperature is needed for the vapor pressure to reach the surrounding pressure, and the boiling point is elevated.

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.
