The purpose of this project is to find out how table salt affects the boiling temperature of water. Our hypothesis is that when adding table salt to boiling water will cause the water to boil at a higher temperature. The materials we'll be using to do this project will be: table salt, water, 2 quart cooking pot, pint measuring cup, teaspoon and tablespoon measuring spoons, thermometer, and a stirring spoon. The experimental procedures are (1) Boil on quart of water on the stove. (2) Measure the temperature of the boiling water. Record the highest temperature reading. (3) Measure out table salt using a kitchen measuring spoon. (4) Add the measured salt to the boiling water and stir. (5) Measure the temperature of the boiling water with the salt in it. Record the highest temperature reading. (6) Repeat for other amounts of salt. The experimental observation were when the salt was added to boiling water it bubbled up more, and then stopped boiling. Afterwards, it boiled again. Our conclusion was that our hypothesis was correct. When adding salt to boiling water will cause the water to boil at a higher temperature. The problems we encountered doing this experiment were that we had trouble reading the temperature of the water. We also had to wear gloves so that our hands wouldn't get hot because once you add salt to the boiling water because the water boils like a volcano irrupting.
