Younger pupils believe that all liquids contain water

Properties of Matter

Misconception RESEARCH REVIEW

Students may use the terms 'liquid' and 'water' synonymously. This may mean that students think of water as a 'prototype liquid', and use it to refer to liquids for lack of their having a more general concept of liquids. It may instead mean that they believe water is present in all liquids as a sort of essence of liquid-type properties, such as 'wetness'.

Some students think that any material melting into a transparent liquid is becoming water (e.g. melting candle wax).
