Answer;
Water has the highest normal boiling point and methanol on the other hand has the lowest boiling point.
Explanation;
-The normal boiling point is the temperature in which the vapor pressure of a liquid becomes equal to atmospheric pressure.If the inter-molecular forces are small, the liquid has a high vapor pressure. Little heat energy will have to be added to separate the molecules, so the boiling point will be low.
-Boiling points and equilibrium vapor pressure are inversely proportional, because less heat is required to raise vapor pressure to reach atmospheric pressure.
-Therefore, since water has the lowest vapor pressure, water it has the highest boiling point and since methanol has the highest vapor pressure it has the lowest boiling point.

Answer:
Drought, resulting in a 65% reduction in water levels.
The solubility KI is 50 g in 100 g of H₂O at 20 °C. if 110 grams of ki are added to 200 grams of H₂O <u>the </u><u>solution </u><u>will be </u><u>saturated</u><u>.</u>
<h3>What is solubility?</h3>
Solubility is a condition where the solute is fully dissolved in the solvent. When fully mixed with the solvent.
Given that 50 g of KI is added to 100 g of water at 20 °C it means 100 g of water can dissolve a maximum of 50 g of KCl.
1 g of water will dissolve an quantity of 0.5 g of KCl.
To assay for 200 g of water: 200 g of water can disintegrate a maximum of (0.5) x 200 g of KCl.
The maximum amount of KCl that will dissolve is 100 g
Actualised amount dissolved = 110 g
when Amount dissolved > Maximum solubility limit
110 g > 100 g
Thus, the solution is saturated.
