Final answer:
Laboratory experiments utilize various flasks such as Erlenmeyer flasks, round-bottom flasks, beakers, and test tubes, each designed for specific purposes like mixing, boiling, stirring, and holding samples. All these options applicable.
Step-by-step explanation:
In a laboratory, various types of flasks are used depending on the specific requirements of the experiment. The types of flasks you mentioned include Erlenmeyer flasks, round-bottom flasks, beakers, and test tubes.
An Erlenmeyer flask, sometimes referred to as a conical flask, has a wide base that tapers to a narrow neck, which makes it suitable for mixing liquids with less risk of spilling. A round-bottom flask is typically used for heating or boiling liquids evenly.
Beakers are cylindrical vessels with a flat bottom used for stirring, mixing, and heating liquids. Test tubes are cylindrical tubes with a rounded bottom and open top, suitable for small-scale reactions, culturing microorganisms, or holding samples.
Each type of glassware serves a distinct purpose in the lab, and the choice depends on the experiment's protocol.
