Robert Boyle did not believe that water was one of the basic elements that all substance was made of. To test this, he conducted an experiment where he ran an electric current through water. He placed two test tubes above each of the terminals of the electricity source and collected that gas that came out. He repeated the experiment a total of three times, each time using the same amount of water and the same level of electric current. His experimental results are shown to the left.

The statement "Robert Boyle did not believe that water was one of the basic elements" is an example of a __.

a)

conclusion

b)

independent variable

c)

hypothesis

d)

constant
