Morphology
round-bottom + flask
The meaning is directly derivable from its parts: 'round-bottom' (a rounded lower shape) modifies 'flask' (a container), so the phrase simply denotes a flask with a rounded bottom. This is a transparent noun‑modifier compound following common English composition patterns and is cross‑linguistically obvious, so a B1 learner who knows the constituent words will understand it.
Etymology
Round-bottom flask gets its name from its shape: a glass vessel with a round bottom and a narrow neck. Because the round bottom helps heat spread evenly and liquids mix well, the name reminds us it is 'used in labs' for heating and mixing chemicals.
