Thread: Hypothesis Information??

Q: When a piece of cloth is dipped in water, the level moves up in the spaces between fibres as shown in the diagram below.
Write an hypothesis that would explain how water rises higher in some types of cloth than others.

What type of information could i use as my hypothesis?? I suppose i could include: If you look at a glass of water, you will notice that the surface curves up at the edge. It's like the water is trying to climb outta the glass. It's because the water particles are strongly attracted to the glass particles. But the glass particles can't move because they are a solid, so the water does the moving.

well, you can begin that way. i think what you are talking about is Capillary action

the water molecules are more attracted to the molecules of the cloth than to each other (i guess you can talk about intermolecular forces and all that here). the water moves up farther in some cloths than others simply because water molecules are actracted to some materials more than others. it also depends on how absorbant the cloth being used is

Okay thanks I'll defidentally include that!
