In an investigation of sugar dissolving in hot water what type of variable is water temperature?

Answer and explanation

Correct answer: Independent variable

In this investigation, the water temperature can be deliberately changed to observe its effect on the time taken or rate at which sugar dissolves. Therefore, water temperature is the independent variable. The dissolving time or rate is the dependent variable because it changes in response to temperature. Exam tip: the factor deliberately changed by the experimenter is the independent variable.
