In an experiment both temperature and time are recorded but temperature is changed. What is the correct identification?

Answer and explanation

Correct answer: Temperature is independent and time is dependent

The governing concept is determined by the role of a quantity in the investigation, not merely by whether it is recorded. Temperature is deliberately changed by the investigator, so it is the independent variable. Time is then measured as the response or outcome, so it is the dependent variable. Option C correctly identifies these different roles. Recording a value does not automatically make it dependent; the experimental purpose and procedure decide its classification. Both cannot be independent if only temperature is manipulated, and temperature cannot be called controlled when it is intentionally varied. Therefore C is the unambiguous answer.
