Question 1.
What is the definition of the surface area to volume ratio?
Show hintHide hint
Consider what happens to surface area and volume as size decreases.
Question 2.
Why do nanoparticles have more reactivity compared to bulk materials?
Show hintHide hint
Think about the relationship between size and surface area.
3Question 3.
What happens to the ratio of surface area to volume as objects become smaller?
- It increases
- It decreases
- It stays the same
Show hintHide hint
Think about how much surface remains relative to space as size goes down.
4Question 4.
True or False: Nanoparticles have lower reactivity than bulk materials.
- True
- False
Show hintHide hint
Recall the principle of exposure in chemical reactions.
Question 5.
Propose a theoretical application of nanoparticles in environmental remediation. Discuss how their surface area to volume ratio would enhance their effectiveness.
Show hintHide hint
Consider how increased surface area can improve interactions.
Question 6.
Compare and contrast nanoscale materials with bulk materials in terms of their melting points. What factors contribute to differences in melting behavior?
Show hintHide hint
