Question: 1 / 400

For what purpose is a crucible primarily used?

Cooking food

Conducting high-temperature chemical reactions

A crucible is primarily used for conducting high-temperature chemical reactions because it is specifically designed to withstand extreme heat and facilitate the melting or chemical transformation of materials. This makes it an essential tool in laboratories and metalworking. Crucibles are usually made from materials such as porcelain, alumina, or graphite that can endure high temperatures without breaking down or reacting with the substances contained within.

While cooking food, storing liquids, and pouring substances might involve other types of vessels or equipment, they do not capture the primary function of a crucible, which focuses on its capability to handle intense heat and support the processes of fusion or chemical experimentation.
