FAQs & Answers
- What is the meniscus and why is it important in measuring liquid volume? The meniscus is the curved surface of a liquid in a container. Reading the measurement at the bottom of the meniscus at eye level ensures an accurate liquid volume reading.
- Which tools provide the most accurate liquid volume measurements? Graduated cylinders and measuring cups are common, but for higher accuracy, especially in labs, pipettes and burettes are recommended.
- How do you read liquid volume at eye level correctly? Position your eyes level with the liquid’s surface and read the measurement at the lowest point of the meniscus to avoid parallax errors.
