Capillarity and Surface Tension | Surface Tension | Physics

[@shubhamupman7260]

Wow great explanation. So simple and easy to understand especially with the examples. Thanks

[@neil_surya]

This was such an informative video. BTW, at the end of the video, I noticed a very large bug of some kind running along your shelf.

[@fidakhanchey]

Observation skills 👍🏼👍🏼👌👌👌👏👏👏😂

YES... A Bug was running on your shelf 😜😜🐛🐛

Pay attention to the class lmao

Thanks for this. I have to do a lab at home for school, but don’t have any capillary tubes, so this helped a lot.

[@himankberwal]

great video for understanding the practical concept !!

[@Attalla-t9b]

Thanks for showing us the experiment!

[@karthikreddyvangeti6790]

Good information Slight correction that it's not the capillary action which makes the water to reach the top of the tree, as the xylum tubes can rise only 1m with the given diameter. So it's the negative pressures that it is being created at the leaves when it evaporates and also the continuous column of xylumn tubes which are filled with water from the beginning without presence of any air bubbles.

[@pablo9364]

Yes agreed. Well he was nearly right

[@Ekta.Prasad_.]

Thanks sir ✨ Such a informative video

[@simonriley4180]

Thank you for the easy explanation

[@MohaMMaDiN55]

How is that the capillary action used to remove sweat from the surface of skin?

[@TheUrbanPinoyBoy]

when sweat is formed the fibrous mesh has small diameter pores that pull the sweat from your skin. lol sorry for the year response XD

[@Nishantk10]

[@ShareInfos516]

That was a well explained video. Thanks

[@shivambhandare2077]

why does the solution in capillary tube occur to be transparent even though the solution is yellow?

[@darrencen6934]

I began to understand what is capillary action , thanks to fountain pens

Very nicely explained video. Short and to the point. Loved it. Thanks

[@physicsphilia5997]

Can I use some parts of it for my KZbin video

[@Civilclips]

thank you sir this helped me in visualisation

[@esecallum]

can you use it to sterilize water??

[@apl.2018]

I bet no one else noticed the bug on the top shelf almost at the end of the video 😎🤣

[@beunited2069]

Why it don't continue to rise and come out why it stops after a certain height

[@visiblehuman3705]

Eventually the force of gravity overtakes the attraction of the water to sides of tube I believe, that’s why with a more narrow tube it can go higher.

[@tridevjha255]

What if the width of the Tube is infinitesimally small will the water reach all the way to top .

[@neethandwrittennotes6196]

Thank you..to the point and helpful 🙏

[@yhtawsa]

Quick and easy video. Thank you sir.

[@pratapsinhasingh8040]

It was such an amazing explanation .☺

[@shivamuniyal6680]

Very helpful video

[@anthonytovar6768]

Why would it go higher with a thinner tube?

[@MohaMMaDiN55]

Anthony Tovar I think as my teacher told me is that when the weight of the water in the strew becomes equal to its surface tension force that’s acting upward, the water level stops from flowing. that’s why as a narrower the strew is, the level of water is higher.

[@Fuphu]

If you blow through a star with a big opening on either end the wind on the other side will be weak, if the straw has small openings then the wind tends to be stronger. That's the basic idea.

[@vbstein2]

The height of the water is defined by when the capillary forces (i.e., the adhesive forces described in the video) balance the gravitational pull on the water. The capillary forces are proportional to the circumference of the tube. The weight of the water is governed by the volume of water that is pulled up the tube, which is proportional to the cross-sectional area of the tube. The ratio of the circumference to the cross-sectional area is 2*pi*r / pi r-squared. As r gets small, this ratio becomes large. As r gets big, the ratio becomes small (i.e., at infinite radius, the ratio goes to zero).

[@siddid7620]

what magic water are you using, I can not recreate these results at all.

[@viveknat777]

does water rise in a capillary tube with blind end at the top?

[@MVBPRINSKUMAR]

No

[@vbstein2]

I think it would rise, but not as high. Without a blind end, the height to which the water rises is governed by the when the force of gravity acting on the water column balances the capillary pressure (which arise from the adhesive forces described in the video). With a blind end, as the water rises (due to the capillary pressure), the gas in the tube would become compressed, and the resulting increase in air pressure would also act to limit the height to which the water rises, in addition to gravity.
