Question 1.
What is a quantum dot?
Show hintHide hint
Think about how size affects what we see.
Question 2.
Why does a nanoscale material have a higher reactivity?
Show hintHide hint
Remember: Smaller means more surface per volume.
3Question 3.
What happens to energy levels as materials approach nanoscale dimensions?
- They become continuous
- They become quantized
- They become random
Show hintHide hint
Think about how small scales change typical behavior.
4Question 4.
True or False: Nanomaterials have a lower surface area to volume ratio than bulk materials.
- True
- False
Show hintHide hint
Consider the differences in size and surface area presented.
Question 5.
A researcher is designing a new drug using nanoscale materials. Discuss how quantum effects may affect the drug’s efficacy.
Show hintHide hint
Consider how size impacts interaction at cellular levels.
Question 6.
Analyze how surface effects can change the mechanical stability of a material when converted to nanoscale.
Show hintHide hint
Think about how more surface area means more interactions with external forces.
