Question

To determine the boing point of a liquid, a student heats 10 mL of the liquid in a test tube and records the temperature every minute for 20 minutes. In this example, time is the what?

The choices are:
Independent variable
dependent variable
hypothesis
control

Is it dependent variable?

Answer 1

well does the temperature change because time passes,

or does time pass because the temperature changes?

Looks to me like the temperature depends on time, not the other way around.

SO, parsing my convoluted logic, which is independent?

Answer 2

Hypotheses

Answer 3

Yes, in this example, time would be the dependent variable. The temperature measurements are being recorded over a set period of time (20 minutes) to observe how it changes, making time the variable that depends on the actions being taken (heating the liquid) and the measurement being observed (temperature).

Answer 4

Yes, in this example, time is the dependent variable. The dependent variable is the one that is measured or observed during an experiment and is expected to change as a result of the independent variable. In this case, the independent variable is the heating of the liquid, and the dependent variable is the temperature, which is being recorded at different time intervals (every minute for 20 minutes).
