What is the term for a substance used to provide cooling, such as in a refrigerator?

Refrigerant
Regeneration
Rust
Roughage

The correct answer is: Refrigerant

A Refrigerant is a chemical substance used in refrigerators to provide cooling. It works by absorbing heat from one place and releasing it in another. This allows the fridge to maintain a cool temperature and keep its contents fresh. Regeneration, Rust, and Roughage are all incorrect options because they do not describe a substance used for cooling in a refrigerator. Regeneration refers to the process of restoring something to its original state, Rust is a natural chemical reaction that causes iron to corrode, and Roughage is a dietary term for foods that are high in fiber. None of these options are related to cooling substances in refrigerators. Therefore, A Refrigerant is the correct answer.
