Question

sanitization can be accomplished by all of the following means except: chemical air drying heat hot water

Explanation:

To determine which option is incorrect for sanitization, we analyze each:

• Chemical: Chemical agents (like disinfectants) are used for sanitization.
• Heat: High temperatures (e.g., in autoclaves) sanitize by killing microbes.
• Hot water: Can sanitize (e.g., in dishwashers).
• Air drying: Just dries, doesn't kill microbes/sanitize. So air drying is the exception.

Answer:

Air drying
