Bulk and surface properties of matter including nanoparticles (chemistry only)
Question
- A. They can provide a stronger scent
- B. They can enhance antibacterial properties
- C. They can make the product more colorful
- D. They can increase the volume of the product
Answer
The correct option is They can enhance antibacterial properties. This answer is correct because it matches the approved learning objective to (chemistry only) Describe that nanoparticles have applications in cosmetics, sun creams and deodorants in the subtopic Uses of nanoparticles.
Explanation
The correct option is They can enhance antibacterial properties. They can enhance antibacterial properties is correct because it directly supports the approved learning objective to (chemistry only) Describe that nanoparticles have applications in cosmetics, sun creams and deodorants. This belongs to the subtopic Uses of nanoparticles within Bulk and surface properties of matter including nanoparticles (chemistry only), so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Uses of nanoparticles.
Common mistake
Misunderstanding Applications of Nanoparticles
Students often state that nanoparticles are only used in cosmetics without mentioning sun creams and deodorants.
To fix this, students should remember to include all applications of nanoparticles in cosmetics, sun creams, and deodorants when describing their uses.
