What is the following is achieved with moist heat, dry heat, gas, or chemicals

Sanitization reduces the number of microorganisms to a safe level, as determined by public health standards, but does not necessarily eliminate all pathogens. This process is often achieved through cleaning methods and lower heat treatments, making it less rigorous than sterilization. Therefore, sanitization does not guarantee complete microbial destruction.

Disinfection involves the use of chemicals or heat to destroy most pathogenic microorganisms, but it may not kill all spores or resistant forms. Disinfection is effective against a wide range of pathogens and is commonly used on surfaces and instruments; however, it falls short of the total eradication achieved through sterilization.

Decontamination refers to the process of cleaning or treating materials to remove or neutralize contaminants, including pathogens. While it may involve steps toward sterilization, decontamination does not guarantee the complete elimination of all microorganisms, which is the defining characteristic of sterilization.
