Which glassware is typically used for boiling or heating liquids?

The round bottom flask is commonly used for boiling or heating liquids due to its shape, which provides even heat distribution. The rounded bottom minimizes the risk of hot spots that could lead to breaking the glass when heated. Additionally, the flask’s design allows for efficient stirring or shaking of the contents while providing easy access for heating over a flame or in a water bath. This makes it an ideal choice for experiments that require the heating of liquids safely and effectively.
