Physical Cleaning is most closely associated with which activity?

• A. Mopping
• B. Disinfecting
• C. Labeling
• D. Centrifuge

Answer: (A)

Physical cleaning means removing soil and debris from surfaces through mechanical action rather than killing germs with chemicals. It focuses on the physical action of washing away grime. Mopping fits this idea perfectly because it uses a damp mop to physically lift and remove dirt from floors, reducing visible soil and potential contaminants. Disinfecting, on the other hand, relies on chemical agents to destroy pathogens and isn’t primarily about removing soil. Labeling isn’t a cleaning action, and a centrifuge is a lab device for separating substances, not cleaning. So the action most closely aligned with physical cleaning is mopping.
