This called "quality content". Thank you so much you saved my day!

[@stormingsharks]

How convenient is it, that I missed the chemistry lecture explaining these IMF relationships for liquids (don't ask me how, it's embarrassing), just to see Professor Dave upload a detailed concise video explaining them the very next day? You're my favorite, Dave.

SImple and clear. I must have learned all this in high school, but until seeing your video I could not explain it. Excellent video. Probably not for the the complete novice, but excellent for a student studying the subject.

I started working in architecture 8 mos. ago and when I first started, the detailed drawings of how specific assemblies go together looked so alienesque. I've been learning that a building goes together the way it does largely to mitigate the intrusion of different environmental forces like moisture, sun, and wind that work to deteriorate a building. The more effective a bldg is at resisting these natural forces(due to being assembled correctly with appropriate materials), the less money the owner/operator of the building has to pay over time in maintenance/repairs. When you own a home, you essentially operate a building and part of being able to afford a home not only includes paying the mortgage and taxes, but also the cost of maintaining the home itself. With that being said, certain parts of a roof is designed the way it is not for aesthetics, but due to surface tension and capillary action that wants to drive water into the building that must be repelled by thoughtful design...that can also look nice as a secondary function. Before starting architecture, I had no idea how much building science informs design.

[@davoodbarzegari4080]

thank you for the very simple explanation. I am an engineer and used the concepts for years but I understood completely now.

Thx professor! when I get my high school degree you'll definitely be one of those who has helped. And helped a lot!

[@jayantpunia4137]

Dude, I love the content you show.

[@ibrahimsalih1512]

This is really the most helpful explanation I've ever come across

[@PGIFilms]

When I was taking my General Chemistry courses I was *heavily* watching chemistry videos on KZbin (2-3 hours a day for about a year: you, Bozeman Science, Tyler Dewitt, The Amoeba Sisters, Khan Academy, Cody's Lab, Nurdrage, NileRed, etc.) and saw just about every one of your older chemistry vids. Was wanting to maintain and build on my chemistry knowledge (Gen-Chem was my science elective for my Associate degree in Business and thinking about going back to pursue a more advance science degree) so it came as quite a shock when I saw the new haircut... I suppose it cuts down the countless "Thank you chemistry Jesus!" comment that I kept seeing on you vids. =P This vid really added to my knowledge since my Gen-Chem courses did not have any detailed emphasis on these liquid properties, they were covered briefly in lecture, but was never put in a quiz or test.

[@erbterb]

Density is related to concavity as radiation is related to convexity? A gas through a viscous material presses away from gravity convexity to get to a more concave state in the surrounding gas. Take schampo and watch air bubbles move away from centre of earth at speeds dependent on bubble size.

Could someone help me with two questions? 1) Why does not water want to reduce the amount of hydrogen bonding occurring by increasing the surface area? 2) Why does to maximize hydrogen bonding let the system to sit at the lowest energy possible?

[@aminakhalid2197]

[@jothi4u]

@5:40 surface tension tends to minimize surface area right? but video says tends to increase surface area.

[@ProfessorDaveExplains]

yes it minimizes it, so energy is required to increase it, by say, puncturing the surface.

[@julesderuelle7819]

Hey Dave! Thanks for the video :). I was wondering if you could answer a question. If I put water in a non-polar container, such as plastic, would that mean the meniscus would become convex since the cohesion is greater than the adhesion? P.S. I as asking this because when I google this situation it says that the meniscus would be neither. It says it would be flat?!

[@tom_winguill]

A convex surface will be formed with decreased level of height than the rest of the liquid

8:39 , doesn't that happen because of the atmospheric pressure pressing on the wanter on the outside of the tube ?

[@nyasajain837]

PeKame PeKame no because u can see the tube is itself open so the surface it is at atmospheric pressure I think u are talking about the mercury experiment in which the tube is closed and has vacuum created inside it
