What term is used to describe a room or building where scientific tests and experiments take place?

The term used to describe a room or building where scientific tests and experiments take place is "laboratory." Laboratories are specifically designed to conduct experiments, analyze substances, and perform various research activities. They are equipped with specialized tools, equipment, and safety measures to facilitate these processes.

In contrast, hospitals and clinics are primarily focused on patient care and medical treatment, while an office is generally a workspace for administrative activities rather than scientific research. Thus, the laboratory stands out as the appropriate term for a facility dedicated to scientific inquiry and experimentation.
