Capillary Action: Comparing B vs D

In summary, capillary action is the movement of liquids through narrow spaces or tubes, such as in a plant's stem. B and D refer to the shape of the tube, with D-shaped tubes resulting in stronger capillary action due to the narrower opening. Capillary action only occurs in liquids and is used in everyday items like sponges and paper towels, as well as in technologies such as inkjet printers and lab-on-a-chip devices.

How is B more correct than D? Both show that forces between glass and fluid are stronger than those between fluid molecules. Thank you for any insight!

B. because on the outside. there is more fluid. therefore. more weight that is the fluid putting on the glass. but on the inside. less fluid and the same surface are touching the tube! so it would be easier for the fluid to rise inside the tube. this question is really common sense! i never did this stuff. but its obvious!
 

What is capillary action?

Capillary action is the process by which liquids move through narrow spaces or tubes, such as the tiny tubes in a plant's stem.

What is the difference between B and D in capillary action?

B and D refer to the shape of the tube or container in which the capillary action is taking place. B-shaped tubes have a wider opening, while D-shaped tubes have a narrower opening.

Which shape, B or D, results in stronger capillary action?

D-shaped tubes typically result in stronger capillary action because the narrower opening creates a greater surface tension, allowing the liquid to rise higher.

Can capillary action occur in non-liquid materials?

No, capillary action can only occur in liquids because it relies on the cohesive and adhesive properties of liquids to move through narrow spaces.

How is capillary action used in everyday life?

Capillary action is used in many everyday items, such as sponges, paper towels, and plants. It is also used in technologies such as inkjet printers and lab-on-a-chip devices.
