Which of the following describes the properties of nitrous oxide?

Nitrous oxide, commonly known as "laughing gas," is correctly described as colorless, odorless, and non-flammable. This gas is widely used in dentistry and medicine, particularly for its anesthetic and analgesic properties.

The combination of being colorless and odorless makes nitrous oxide easy to administer without alarming patients, as they are often unaware of its presence. Additionally, its non-flammable nature ensures safety during its use in various medical procedures, distinguishing it from other gases that may pose a fire hazard.

Understanding the properties of nitrous oxide is crucial for healthcare professionals to ensure a safe and effective application in clinical settings.
