What is the purpose of keeping the eye at the level of the meniscus while reading liquid volume?

Answer and explanation

Correct answer: Reduce error caused by viewing angle

The direct answer is B, reducing error caused by the viewing angle. A liquid surface is usually curved at the edge; this curved surface is called the meniscus. If the eye is above or below it, the line of sight makes the level appear different. This is parallax error. Keeping the eye level with the meniscus makes the sight line nearly horizontal and gives a more accurate reading; for water, the bottom of the meniscus is normally read. Option A is wrong because eye position does not change liquid colour. Option B is correct. Option C is wrong because it does not enlarge the container. Option D is wrong because reading correctly cannot increase the liquid volume. Exam cue: eye level with meniscus means less parallax.
