Title: Does water with salt boil faster than plain water?

Statement of Problem: Will water with salt or plain water boil faster?

Hypothesis: If salt is added to water, the salt water would boil faster than the plain water.

Background Information: Water is a basic molecule made up of two hydrogen atoms, and one oxygen atom. When these three atoms come together, they form a strong bond that is difficult to break. The strength of this bond keeps a water molecule together for millions and even billions of years. Common table salt, or sodium chloride, is the chemical compound NaCl.

Procedure:
1.Place 4 cups of water in a pot and add 1 tablespoon of salt. 2.Turn on stove to high heat.
3.Place pot on stove and observe until water starts boiling. 4.Repeat steps 1 through 3 using plain water.

Materials:
1 pot
8 cups of water
1 tablespoon of salt
1 measuring cup
1 measuring spoon
Data/Observation:
Both the salt water and plain water took eight minutes to start boiling.

Conclusion:
Based on the analysis of the data gathered the results conclude that both salt and plain water took approximately the same amount of time to boil, thus the hypothesis was not accepted. Possible errors include the amount of salt used was not enough to make a difference.

Acknowledgements:
I would like to thank my parents for supplying the materials and showing me how to construct the project.

Recommendation:
I recommend changing the following: add more salt to the water.
