Morphology
The meaning is directly compositional: a thermometer that uses alcohol as the working liquid. The noun-noun combination (liquid + instrument) follows a common, cross-linguistically transparent compounding pattern, so a B1 learner who knows 'alcohol' and 'thermometer' can infer the meaning.
Etymology
Alcohol thermometer comes from the simple picture of a glass thermometer filled with alcohol that expands when it gets warm and rises in a thin tube. The rising, colored alcohol is the image people see to 'show the temperature', and because alcohol stays liquid at lower temperatures and is safer, the name now means 'a thermometer that uses alcohol'.
