Question

# A student conducts an experiment to determine how the temperature of water affects the time for sugar to dissolve. In each trial, the student uses a different amount of water and a different temperature of water. What is wrong with this experimental design? The student did not change enough independent variables. The student changed more than one independent variable. The student does not have a dependent variable. The student needs to perform more trials.
