In an experiment, a student wants to know the boiling point of a solution of sugar water. The student first measures the boiling point of 100 mL pure distilled water. Then she measures the boiling point of 100 mL of pure distilled water plus 10 grams of sugar. The student uses a Bunsen burner to heat both solutions. Which is the experimental variable?

Answer:

Amount of sugar

Explanation:

An experiment has an experimental variable and a control variable. The amount of sugar is experimental variable in the give experiment. Here, boiling point of sugar solution would change in accordance to changes in the amount of sugar. Amount of water serves as control variable and is kept constant throughout the experiment.

Answer:

The correct answer is "amount of sugar"

Explanation:

In an experiment we can identify the experimental variable by analyzing which variable is not affected by the conditions of the others, and usually, is the one that is tested with different quantities while the other variables remain constant. In this example, a student wants to know the boiling point of sugar water, therefore she measures the boiling point of 100 mL of pure distilled water plus 10 grams of sugar in comparison to the boiling point of 100 mL of pure distilled water only. In this case the experimental variable is the amount of sugar. We can conclude this because is the amount of sugar is added independently of the other variables and is the one that is tested with a defined quantity while the other variables remain constant.
