Detailed explanation-1: -Bacteria multiply rapidly between 40 and 140 degrees. Bacteria will not multiply but may start to die between 140 and 165 degrees. Bacteria will die at temperatures above 212 degrees.

Detailed explanation-2: -Although using normal cleaning products can help reduce bacteria on household surfaces, disinfectants can kill them. Some examples of disinfectants that can kill bacteria on surfaces include: products that contain alcohol, such as ethanol and isopropyl alcohol. household bleach.

Detailed explanation-3: -Air temperature is key for bacteria. In general, cold air kills germs while warm air incubates them.

Detailed explanation-4: -Moist heat destroys microorganisms by the irreversible coagulation and denaturation of enzymes and structural proteins. In support of this fact, it has been found that the presence of moisture significantly affects the coagulation temperature of proteins and the temperature at which microorganisms are destroyed.
