Question

A measuring cylinder is used to measure the volume of a quantity of water. Which measuring technique would not improve the accuracy of the measurement? A making sure that the measuring cylinder is vertical B making sure that the water surface is at eye level C reading the top of the water meniscus D using the smallest measuring cylinder available that will contain all the water

Answer 1

C) reading the top of the water meniscus

Meniscus is the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension. This means that water forms a downward meniscus so we have to read the downward value to improve the meniscus.
