Show hintHide hint
Think about how small objects can float on the surface of water.
Question 2.
What is capillarity?
Show hintHide hint
Consider how a paper towel absorbs water.
3Question 3.
What is the primary factor causing liquid to rise in a capillary tube?
- Gravity
- Surface Tension
- Fluid Weight
Show hintHide hint
Consider forces acting on the liquid in a tube.
4Question 4.
True or False: The diameter of a tube affects the height to which a liquid can rise due to capillarity.
- True
- False
Show hintHide hint
Think about your experiences with straws.
Question 5.
A thin glass column is used to measure the height of water (surface tension = 0.0728 N/m). The diameter is 2mm. Calculate the height to which water will rise in the column.
Show hintHide hint
Convert diameter to radius and ensure unit consistency.
Question 6.
In a situation where two different liquids are involved, how would you approach calculating the equilibrium height in a shared capillary tube?
Show hintHide hint
Start by establishing the individual contributions of both fluids before combining them.
