By adding salt it means that you are adding an impurity into the water. Impurities can lower the boiling point, while increasing its melting point.
Any added impurity can change the boiling point of a liquid.
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
The boiling point of water will increase if gelatin will be added to the water. The reason for this is because gelatin adds to the concentration of the liquid resulting to higher boiling point.
Any material added to water raise the boiling point.
increases
cold water heating up to its boiling point a physical change or a chemical change
it cools it
sugar
No, boiling point is not affected by volume. What will change is the amount of energy you need to put in to get it to boiling point.
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
it does not change
Yes, Salt also lowers the freezing point of water, and lowers the boiling point of water. Add salt to a boiling pot of water and it immediately boils faster/harder at the location that the Salt hit the water.
