Challenge Problems
Push your limits with challenges.
Question 1
Determine the pressure difference inside a soap bubble of radius 1 cm, given that the surface tension is 0.03 N/m.
💡 Hint: Remember this is a bubble, so you must use the correct formula that accounts for two surfaces.
Question 2
If a glass tube of diameter 2 mm shows a height of liquid rise of 5 cm, calculate the surface tension assuming the density of water is 1000 kg/m^3.
💡 Hint: Make sure to convert all units properly.
