The temperature of a liquid was recorded every two minutes. Which statement is a direct observation?

Answer and explanation

Correct answer: The temperature rose from fifty degrees to sixty-two degrees in six minutes

A direct observation is information obtained by measuring or seeing something during the investigation. In this situation, the temperature was recorded at regular intervals, so a statement that reports the measured change is directly supported by the observations. Option C states that the temperature increased from fifty degrees to sixty-two degrees in six minutes. This is a record of measurement, not a prediction or an explanation.

Option A predicts that the liquid will boil, so it is an inference about the future. Option B proposes an unseen explanation involving invisible energy, which was not directly measured in the description. Option D makes a vague claim about the liquid’s nature rather than reporting a recorded result. Therefore C is the correct choice because it uses numerical temperature readings collected during the experiment.
