Correct Answer
Option C
Explanation
Option 3 is the correct answer because it states "Measure the boiling temperature as 100┬░C." This is not a suitable indicator to assess the students on this task because the boiling point of water can vary depending on several factors, such as atmospheric pressure and impurities in the water. At sea level, pure water boils at 100┬░C, but ordinary tap water may contain impurities that can alter its boiling point.тАжRead More
