Questions & Step-by-Step Solutions
Which of the following factors does NOT affect the efficacy of a disinfectant?
Step 1: Understand what efficacy means. Efficacy refers to how effective a disinfectant is at killing germs.
Step 2: Identify the factors that can affect the efficacy of a disinfectant. These include concentration (how strong the disinfectant is), organic matter (like dirt or food that can interfere), and temperature (how hot or cold it is).
Step 3: Consider the options given in the question. We need to find out which factor does NOT affect efficacy.
Step 4: Analyze the factors. Concentration, organic matter, and temperature all influence how well a disinfectant works.
Step 5: Determine the factor that does not affect efficacy. The color of the disinfectant does not impact its ability to kill germs.
Step 6: Conclude that the correct answer is the color of the disinfectant.
