Final answer:
The function of a nozzle in the process of air flowing into the atmosphere is to accelerate the airflow.
Step-by-step explanation:
The function of a nozzle in the process of air flowing into the atmosphere is to accelerate air flow.
By using an adjustable gas nozzle, such as in a Bunsen burner, air is entrained to achieve proper combustion. Similarly, atomizers, paint sprayers, and carburetors use nozzles to create a jet of air that entrains and moves respective liquids. These examples demonstrate how nozzles accelerate the flow of air or other fluids.
