A measuring cylinder is a common laboratory instrument used for measuring the volume of liquids. It is designed with a narrow cylindrical shape and has graduated markings along the length of the cylinder to allow for accurate readings.
Justification:
- The graduated scale allows users to read the exact volume of liquid by observing the meniscus (the curve at the surface of the liquid). The measurement is taken from the bottom of the meniscus to avoid errors caused by surface tension.
- Measuring cylinders are ideal for liquids because their shape ensures that the liquid’s volume is uniformly distributed along the length, providing more consistent measurements compared to containers with irregular shapes.
