Round-bottom flask vs distilling flask

Both 'round-bottom flask' and 'distilling flask' are correct, but they refer to slightly different types of laboratory glassware. 'Round-bottom flask' typically refers to a flask with a round bottom used for heating and mixing liquids, while 'distilling flask' specifically refers to a flask used in distillation processes.
