2 cards from this section. Quick, good the night before a test.
What is surface tension?
Think about why droplets form a particular shape.
Why is volume conserved when splitting a droplet?
Consider how matter is not created or destroyed.
What causes a droplet to maintain its spherical shape?
Think about the properties of liquids!
True or False: The volume of a droplet changes when it is split into smaller droplets.
Remember that matter cannot be created or destroyed.
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.
Surface areas formula for spheres is needed.
Investigate how different surface tension values affect the amount of work needed to split a droplet into smaller droplets, both theoretically and experimentally.
Consider comparing results with various liquids and their known surface tensions.
