What may happen if container size changes in every trial?

Answer and explanation

Correct answer: Container size may affect the result

Changing the container size can alter conditions such as surface area, capacity, or heat transfer. Therefore, it may affect the result, so it should be kept constant as a controlled variable in a fair test. Option B is incorrect because changing container size does not ensure that the independent variable remains unchanged. Exam tip: In a fair test, keep all factors other than the independent variable constant.
