Question

which one is the dependent variable? time to dissolve water temperature rewatch

Explanation:

In an experiment, the dependent variable is the one that is measured and depends on the independent variable. Here, water temperature is likely the independent variable (the one we might change), and the time it takes for something to dissolve (time to dissolve) depends on the water temperature. So the dependent variable is "Time to dissolve".

Answer:

Time to dissolve
