Explicação
## Step 1The problem is about colligative properties, which are properties of solutions that depend on the number of solute particles in the solution, not on the nature of the solute. The problem provides three colligative properties: freezing point depression, boiling point elevation, and vapor pressure.## Step 2The first property, freezing point depression, refers to the phenomenon where the freezing point of a solution is lower than that of the pure solvent. This is because the addition of a solute lowers the freezing point of the solution.## Step 3The second property, boiling point elevation, refers to the phenomenon where the boiling point of a solution is higher than that of the pure solvent. This is because the addition of a solute raises the boiling point of the solution.## Step 4The third property, vapor pressure, refers to the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. The vapor pressure of a solution is lower than that of the pure solvent because the addition of a solute reduces the number of molecules that can escape into the gas phase.
