Determine the name of the following piece of lab equipment.
- A.
Filter paper
- B.
Wire gauze
- C.
Funnel
- D.
Heat mat
Correct Answer
B. Wire gauzeExplanation
Wire gauze is a piece of lab equipment used to support a container (such as a beaker or flask) during heating. It is made of a mesh of metal wires, typically woven in a square pattern. The wires provide stability and even distribution of heat, preventing direct contact between the container and the heat source. This helps to prevent overheating or breaking of the container. The wire gauze is commonly used in chemistry experiments that involve heating substances over a Bunsen burner or other heat source.Rate this question:
