Question

a group of students wants to see how temperature affects the time it takes for spilled water to dry up in the investigation what will be the dependent and independent variables

Answer 1

The independent variable is the one that researchers directly change. Here, the students will deliberately change the temperature, so the independent variable will be temperature in degrees. The dependent variable is the one that researchers measure as the outcome of the experiment. Here, the students will measure the time it takes until the water is gone (evaporated), so the dependent variable will be time, in units of seconds or minutes or hours.
