please help anyone who knows what it means

Let me google that for you

Essentially, capillarity are the forces (cohesion and adhesion) that allow water to rise within a narrow tube, without the input of energy. However, some may describe it as being simply the phenomenon of the water rising.

Hope that helps

Wait why is this in the chemistry section? Why do you need to know about capillarity in chemistry?

 

[Carrotsticks]

Yeah it's used in Bio for movement of water through the xylem in plants.

Lol exactly! I've never seen/heard the word capillarity in chemistry, in biology it is used numerous times.

i swear, u must go to my school
this plus the energy considerations thing
...are you doing a chem assignment due tomorrow by any chance?

i got a chemistry assignment and the exact question states what is capillarity

thanks, so is it passive movement?

Capillarity is commonly explored in physical chemistry (it is actually more of a physics concept). It's not just only applicable in plants and biology, for example good sponges that hold water require capillarity.

its in the water topic. capillarity is the tendency of a liquid to rise up or fall down tubes right? well the up and down movement is a result of the unbalanced forces (suface tension) of the liquid. and water has surface tension due to its hydrogen bonding
someone correct me if im wrong please

did u write that on ur assignment?

 

[future-doctor]

Hmmmm capillarity in regards to physics, interesting

Oh yeh thats right the water module. My crap chem teacher probably skipped it like most of the topics in prelim and hsc chem lol.

lol, yep, so hopefully its right :/

u watch water go up the pipe and oil not go up.... something about cohession and adhession forces
