The student made a mistake while making the table. The mistake was

• Forgeting the heading of the independent variable

• Forgeting the unit of the dependent variable

• Forgeting the heading of the dependent variable

• Not using the same decimal places.

• Writting the units inside the table

The student must make a _________ graph to represent the data of this experiment. (line, bar, histogram or pie)

On a Table, the independent variable is always placed on the

• First column

• second column

• First and second column

• None

Using the data of the table a conclusion for this investigation is

• The air temperature of the hydrogen peroxide solution is 22.4 while the air temperature of vinegar is 22.6

• All air temperature are the same for the solutions

• The vinegar and sodium bicarbonate solution register the highest air temperature

• The difference of air temperature between hydrogen peroxide and vinegar was 2 ° C.
