Boiling point is dependent from pressure. Solutes also have a great impact on the freezing and boiling point.

What effects do solutes have on a solvent's freezing and boiling boints?
The effect of a solute on the freezing point and boiling point of a solvent is related to what is known as the colligative property. Upon addition of the solute, the freezing point will be lowered, and the boiling point will be increased. The magnitude of the change will depend on the solute and how many particles it forms upon dissolving, and on the nature of the solvent and the freezing/boiling point constant for that solvent.
When a solute is added to a solvent the freezing point of the solution is?
The freezing point is lowered slightly as some energy is absorbed by the impurities.
How does the boiling point of a solvent change when a solutes is dissolved in?
The boiling point rises and the freezing point lowers.The reason being, when a solute dissolves in a solvent, the solute molecules wedge themselves between the solvent molecules. In order for the solvent to freeze, its molecules have to get close enough together to form a solid. However, the solute molecules are in the way. As a result, it requires much colder temperatures for the solvent molecules to form a solid, despite the hindrance of the solute's molecules. The same sort of thing happens when trying to boil the solvent, only instead of holding the solvent molecules apart, the solute molecules end up holding them together, preventing them from boiling. Therefore, a more energy is needed to break the bond between solvent and solute, which allows the solvent to boil.
How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
Do solutes increase or decrease the boiling point of a solvent?
No; solutes don't decrease the boiling point of the solvent, they increase it! Solutes decrease the melting point of the solvent! Think of it this way: low goes lower (melting point) and high goes higher (boiling point).

Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
raise its freezing point
What will the nonvolatile solute do to the freezing point of a solvent?
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.
What are two ways that solutes affect the properties of solvent?
Solutes lower the freezing point and raise the boiling point of a solvent! :)
How does the presence of a solute affect the freezing and boiling points of a solvent?
They usually lower freezing points, think antifreeze. And salt water freezes at a lower temp than fresh, that is why they put salt on ice. And they raise boiling points, think salt in water when making spaghetti. Or, again antifreeze.
What is freezing point elevation?
This is not a common phenomenon. Usually it is boiling points that are elevated, and freezing points are depressed. It is possible that a freezing point could be raised (elevated) due to the presence of an impurity with a much higher freezing point.Changes in boiling and freezing points are typically due to impurities in compound.See the Related Questions to the left for more information about freezing point depression and boiling point elevation problems.
How adding solute changes the properties of a solvent?
Solutes raise and lower the boiling points of solvents. :)
How are freezing point depression and boiling point elevation useful?
the main applicative use of freezing point depression and boiling point elevation is to calculate the molecular mass of a non volatile solute in a pure solvent.
The physical properties of a solution that differ from those of its solute and solvent include freezing point boiling point and what?
Conductivity

Does adding a solute to a solvent raise the boiling point?
No, generally that would lower the freezing point, not raise it. Salty water freezes at a lower temperature than pure water. And salt can melt ice, which is the same phenomenon.
