The salt reduces the number of water molecules from escaping the surface into the air. Thus, the water has to be at a higher temperature to be able to push the salt molecules aside and finally reach the surface and evaporate.

Why does it take the water longer to boil when it has salt in it?
impurities rise the boiling point
What is your understanding of effects of pressure changes on the boiling point of a liquid?
The effects of changing pressure on the boiling point of a liquid is that the water becomes temperature becomes higher. The boiling point will continue to rise depending on the amount of pressure applied.
Why is water activity a better measure of concentration when calculating freezing point depression or boiling point rise?
0 and 100 0 and 100
Is the melting point of impure water lower or higher than freezing point?
The boiling Point of impure water is 100 degrees celsius
Boiling point for salt water?
The boiling point on saltwater is normally 100 degrees Celsius, (212 Fahrenheit). But it depends on how much salt there is; the more salt, the longer it takes, less salt, less time. Hope that helped!
How does impurities in water effect its boiling point?
Depending on what is in it, the boiling point will either rise or fall.
What does an increase in pressure on the surface of water do to the boiling point?
It will raise the boiling point. This why, for example, car radiators have a pressure cap. This causes a rise in the boiling point of the water and it is less likely to boil.

How are boiling and freezing points of a sample of water affected when salt is dissolved in the water?
the freezing and boiling points rise significantly- this is why when you boil water in a saucepan, like for pasta, it is advised that you put salt in the water so that the water boils at a higher temperature, thus allowing you to heat the water to a higher temperature. hope this helps
Does the temperature lower of boiling water when salt added?
No, if anything (including salt) is dissolved in a liquid (including water), the freezing point will become lower and the boiling point will rise. This phenomenon is part of a class of properties known as colligative properties of solutions.
What will rise from boiling water?
Water vapour, damp or gas
Why doesn't the temperature of water continually increase as it heated?
Temperature doesn't give the whole picture when you talk about boiling. A more useful property to talk about is enthalpy. Enthalpy is the energy held by the water. Prior to the boiling point, enthalpy and temperature both rise linearly. At the boiling point, temperature stops rising, but enthalpy continues to rise until it becomes steam. If you were to continue adding energy to the steam, it's temperature would rise again. The amount of energy that must be added to water to get it from water just at the boiling point to steam is the latent heat of vaporization and is equal to the enthalpy rise discussed in the previous paragraph. The latent heat of vaporization and the temperature where boiling will occur are dependant on the pressure.
Putting salt in water speeds up the boiling process?
No, it will lower the Boiling Temperature of Water. Try this test, bring a pot of water to a slow boil, and sprinkle some salt into the pot. The water will boil "harder" where the salt hits the water.
What would happen to the boiling point of a substance if the elevation were to rise?
Actually, as you rise in elevation in atmoshpere im assuming, the pressure decreases. This pressure drop will cause the boiling point of anything to rise, therefore requiring more energy to boil.
