Challenge Problems
Push your limits with challenges.
Question 1
How much work is required to split a droplet of radius 0.2 m into 8 smaller droplets, each of radius 0.1 m? Assume surface tension is 0.075 N/m.
💡 Hint: Surface areas formula for spheres is needed.
Question 2
Investigate how different surface tension values affect the amount of work needed to split a droplet into smaller droplets, both theoretically and experimentally.
💡 Hint: Consider comparing results with various liquids and their known surface tensions.
