This is simply because the evaporation enthalpy is bigger than the enthalpy of fusion. ΔTf = -Kf · m (m= molality) ΔTb = Kb · m (m= molality) what is important is that Kf is proportional to 1/Enthalpy of fusion and the sam is true for Kb (with enthalpy of evaporation)
Freezing point depression is not a medical term, but a term of physics. It refers to the scientific concept of when the freezing point of a liquid is lowered by adding something to it. For example: The freezing point of water is 0 degrees Celcius, but if salt is added to water, the freezing point is lower, and will still be a liquid at 0 degrees.
To determine which solution has a lower freezing point, you need the concentrations of solute in each solution and their respective properties (molal freezing point depression constants). The solution with the higher concentration of solute and lower molal freezing point depression constant will have the lower freezing point.

This is the modification of melting (freezing) point due to impurities in the material.
This is the property of freezing point depression and boiling point elevation. This is because of the solute absorbing the energy added to the system to heat its own molecules and so it would require more energy to boil the solvent. Likewise for freezing point depression, the molecules retain more energy.
The relationship between freezing point depression and molar mass is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
The relationship between the molar mass and freezing point depression of a substance is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
The relationship between molar mass and freezing point depression in lab answers is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
The relationship between molecular weight and freezing point depression is that as the molecular weight of a solute increases, the freezing point depression also increases. This means that a higher molecular weight solute will lower the freezing point of a solvent more than a lower molecular weight solute.
The freezing point is the temperature at which a liquid turns into a solid, while the boiling point is the temperature at which a liquid turns into a gas. The freezing point is typically lower than the boiling point for a substance.
Freezing point depression is the phenomenon where the freezing point of a solution is lower than that of the pure solvent. This is due to the presence of solute particles, which disrupt the formation of solid crystals. The extent of freezing point depression is determined by the van't Hoff factor, which represents the number of particles a solute molecule dissociates into in a solution. The greater the van't Hoff factor, the greater the freezing point depression. Therefore, the relationship between freezing point depression, van't Hoff factor, and the properties of a solution is that they are interconnected in determining the freezing point of a solution based on the number of solute particles present.
The depression of the freezing point is dependent on the nature of solvent and concentration of solute.
The freezing point depression in a solution is directly related to the Van't Hoff factor, which represents the number of particles formed when a solute dissolves in a solvent. The equation used to calculate the freezing point depression in a solution is Tf i Kf m, where Tf is the freezing point depression, i is the Van't Hoff factor, Kf is the cryoscopic constant, and m is the molality of the solution.
Boiling point elevation and freezing point depression are both colligative properties of a solution. Boiling point elevation occurs when the boiling point of a solvent increases when a solute is added, while freezing point depression happens when the freezing point of a solvent decreases with the addition of a solute. These phenomena are related because they both depend on the concentration of solute particles in the solution, with boiling point elevation and freezing point depression being proportional to the number of solute particles present.
The freezing point depression method can be used to calculate the molar mass of a solute in a solution by measuring the decrease in the freezing point of the solvent when the solute is added. By knowing the freezing point depression constant of the solvent and the amount of solute added, the molar mass of the solute can be calculated using the formula: molar mass (freezing point depression constant molality) / freezing point depression.
The depression of the freezing point is dependent on the concentration of solute particles in a solution. More solute particles lead to a greater depression of the freezing point.
