Which instrument is a container for mixing or heating liquids?

• A. Beaker
• B. Ruler
• C. Microscope
• D. Anemometer

Answer: (A)

In a science setting, a beaker is the container designed for holding, mixing, and often heating liquids. Its wide mouth makes stirring and pouring liquids straightforward, and it’s made to withstand heat when placed on a hot plate or over a flame (when glass). The other tools have different functions: a ruler measures length, a microscope lets you view tiny objects, and an anemometer measures wind speed. So, the beaker is the container intended for mixing or heating liquids.
