2 cards from this section. Quick, good the night before a test.
What is capillarity?
Think of how liquids behave in narrow tubes.
Define surface tension.
Consider what happens at the surface of a water droplet.
What determines the height of capillarity in narrow tubes?
Think about what allows water to rise in a thin straw.
True or False: A larger diameter necessarily leads to a higher capillary rise.
Consider the differences between using a straw or a wide glass.
Calculate the height to which water will rise in a capillary tube with a radius of 0.5 mm and surface tension of 0.072 N/m at an angle of contact of 30 degrees.
Ensure you convert all units to SI before substituting.
Discuss the implications of different liquid densities on capillary rise in various environments, providing examples.
Consider real-life applications where the context may involve varying densities.
