HYPOTHESIS: If salt is added to water, then the water will boil at a higher temperature, because salt makes the water impure.
The Experiment
1. Gather the materials for the experiment.
2. Measure and pour two cups of water into the cooking pot.
3. Place the pot on the stove and turn on the heat.

4. Watch the water as it heats up and wait for it to boil.
5. Measure the temperature of the water when it begins to boil.

6. Add 1 tablespoon of salt to the water and stir it.
7. Watch what happens to the water and take notes.
8. Measure the temperature of the water once it begins boiling again.
9. Repeat steps 6-8 at least 3 times.

Results
The temperature of the boiling water was 213° F before adding salt. When salt was added to the boiling water, I observed that the water stopped boiling for a moment and started back boiling shortly after. When the water began boiling again after the salt was added, it was at a high temperature than before the salt was added. As more salt was added, the water boiled at a slightly higher temperature. My hypothesis was supported by my experiment.
Based on research done online, I discovered that salt is a solute and water is a solvent. When adding a solute to solvent the boiling temperature of the solvent rises because it causes the water to be more impure. This means the water needs more energy to reach boiling point because it has to remove the solute from the solvent before turning into gas when boiling.
