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.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
