This man should be given a Bharat Ratna for his evergreen teaching style and contribution to students’ life

[@_-_LEGEND_-_]

Reason (based on sir's teachings) for this video's last wrods:- “Liquid will rise to the top and change it's meniscus and contact angle, contact angle will start becoming equal to 90°.” When a liquid rises in a capillary tube the surface tension between solid-liquid comes from molecules of solid that are just above the level of the liquid molecules so that when they attract each other the liquid molecules are pulled upwards. So when the water reaches the top there's no solid molecules above the liquid level, hence there will be no force acting upwards. Hope this helps 🙂

[@rajankumar3487]

Lecture's last lines for those who need it.... *Liquid will rise to the top and change it's miniscus and contact angle. Contact angle will start becoming equal to 90°.*

[@Abhishek-vv1yg]

Beauty 📛📛

[@harshchoudhary8407]

Liquid will rise to the top & change it's meniscus radius to a new radius given by R=hr/h' but liquid will not over flow

Last line: Liquid will rise to the top and change its meniscus in such a way that the product of h and R(radius of meniscus) remains constant and liquid never overflows. h=2T/R¶g implies hR=2T/¶g = constant implies hR = constant implies R is inversely proportional to h.

Last part: The radius of curvature of its meniscus increases to a value R' So that R'h'=Rh. Note that contact angle remains constant as it is property of liquid And if we further reduce length of tube then at h'=0 radius of meniscus becomes infinite due to which liquid becomes flat Source : cengage Hope it helps

Angle of contact between silver and water is 90 Here is one more legend.... Best discovery on KZbin..we must promote good trs kzbin.info/aero/PLrsyAZb3slKauN7NpqU7Zh9eSJ71T9417

[@sagarpanwarpranyodha9900]

Yeah bro I also searched your answer for my doubt

[@adityaanshul1838]

The angle of contact and hence the radius of meniscus change to as to rise the liquid to a suitable height such that force because of surface tension equals weight of columns.

[@enthusiasticgamer297]

Unimaginable strategy to give us feel of ‘Why Capillary?’. Mind blowing feelings of how the mathematical derivation came from.

[@musicallyindia9729]

For pure water and perfectly clean glass, the angle of contact is 0°. For ordinary water and glass, it lies between 8° and 18°. For pure water and pure silver, the angle of contact is 90°. When pure water is put in pure silver vessel, the surface of water is flat.

At 32:52 apne btaya pure water k liy theta 0 hota h but sr pichle lecture me apne btaya tha ki pure water k liy contact angle 90 degree hota h .. please tell kya hota

[@jenilshah8042]

Sir 26:45 theta 90 degree hoga na pure water ke liye

[@HarishSumant]

To know why the liquid rises, go directly 21:00

[@sarthakgirdhar2833]

No, it won't overflow. That should be obvious since doing so would create a constant flow, constantly using energy, but without any energy input. Put another way, that would be a perpetual motion machine, one you could actually extract free power from. The same force that pulls the water along the inside of the capillary tube also holds it there when it reaches the end. This force doesn't just pull upward, it pulls the water along the glass. At a certain height, the weight of the water column ballances this pull. In that case the pull is upward since there is water below but not above. In your case, there is nothing to pull the water column higher when it reaches the end of the tube, so it just stays there. The pull only exists at the boundary between water and not-water. The bulk of the water in the tube isn't being pulled any particular way. Credits- Olin Lathrop (Physics Stack Exchange)

Small trick is that make your conical flask straight by adding alpha/2 So formula becomes theta+alpha/2

@@jatt_station also mention the time about which u r talking ...

[@jatt_station]

@@Shayka_khan numerical k soln mein...numericl started from approx 30:00 cos theta = zero,, yeah kaise aaya becuz pehle toh sir ne bola tha k in pure water theta is 90 degree,,means to say contact angle 90 degree

@@jatt_station at 90 degree the value of cos is zero . Cos 90 = zero .
