What is a beaker used for in science?

A beaker is a cylindrical container with a flat bottom and a lip for easy pouring. It is commonly used in laboratories for holding and measuring liquids. Beakers are usually made of glass, but can also be made of plastic or stainless steel.

Beakers come in a variety of sizes, typically ranging from 50 ml to 1000 ml or more. They are marked with graduated markings to indicate volume measurements, although they are not as precise as graduated cylinders for measuring exact volumes.

Beakers are commonly used for mixing, heating, and storing liquids in various scientific experiments. They are not as accurate for measuring volumes as other types of glassware, such as graduated cylinders or volumetric flasks, but they are versatile and easy to use for a wide range of applications.
