It's very simple. But as you have asked, I will elaborate. Density here is number of water molecules per let's say square mili meter of the surface. Without surfactants it's only water molecules on the surface. So their density is high. However, when surfactants are there, they displace water molecules. Or in simple words, the same surface area is shared by both, surfactants and water molecules. So obviously less number of water. molecules would be there is the same square mili meter of the surface. It's like let's say 100 homes are there in 1 square kilometre of a city and each one is occupied by a doctor. So we have 100 doctors is 1 square kilometre. But then 10 lawyers came and replaced 10 doctors from 10 homes. So now we have only 90 doctors per square kilometre. I hope it's clear now.
There is no dedicated video but videos "Phospholipids in water" and "membrane proteins" might help. Search for these title in our channel. I hope that gives you some idea.
I still don't get it ☹️☹️☹️ Why surface tension increase collapsing pressure when there is a pull downwards and in-between them on surface.... When molecules are pulled downwards they should reduce collapsing pressure????
I understand your confusion. Think step by step. Downward pull tends to reduce surface area. Now image what would happen if surface area decreases... Collapse.! I hope this helps.
Or forget downward pull. You understand that there is tension between molecules on the surface right!. Now just think what all these tense molecules would do? They will try to come closer. And as the do so, there is collapse.
it's always that one Indian dude on youtube that saves the day lmao
Ki
Always
hahah yup
beautifully explained....Being a visual learner, this single video made this concept clear for me.....thanks..
Most welcome. Please share the video.
@@NonstopNeuron hi sir can you please explain how biosurfactants have antibiotic property and how do we extract them without losing it's activity
finally someone who explains the forces between molecules, thanks
This is the best explanation ever! 😭Thank you!
Thank you 😊
you are the only Indian bio teacher I subscribed on youtube, despite your accent everything else are well explained!
Dude, you have definitely reduced my tension headache on this topic!
Very well explained in very short time. Good work keep it up sir 👍👍👍
Can't stopped myself from commenting! 🙌
Thank you 😊
Perfectly clear 💎thank you ❤
Thanks! Quick and clear explanation :)
Excellent presentation!!! Thanks
Glad you enjoyed it!
Amazing.
Love your lecture from Hanoi Medical University in Vietnam
I was in Hanoi this January. Loved the trip to Vietnam.
@@NonstopNeuron It's wonderful
Always Easy to understand....
Keep it up....
Thank you 😊
great explanation!! Thank you!
Great explanation, thank you very much
awesome explanation!
Excellent presentation. Thank you very much sir
Outstanding! Thank you so much for sharing this.
Great explanation thank you!
Thank you sir, excellent video
Thank you sir for this wonderful lecture
No other video I that I watched allowed me to get a nicer basic idea of how surfactant works: and how surface tension occurs in alveoli
well explain God bless you
really nice thanks a lot sir
Great explanation! Thanks a lot.
Thank you very much
God bless you
It's super clear nowwwwww
That great. Happy to know that. Please share the videos. We need your support. Thank you.
Superb and easy
Thanks 😊
amazing video
sare concept clear ho gae
Thank you for your videos! They are always appreciated.
Thank you. Please keep sharing 😊
Thank you so much
Nice explanation
Thank you 😊
I get it now, thank you!
Welcome 😊
Wonderful!
I liked the explanation.
Sir... Can you expand the concept of density?... As of how it reduces density of water molecules on surface
It's very simple. But as you have asked, I will elaborate. Density here is number of water molecules per let's say square mili meter of the surface. Without surfactants it's only water molecules on the surface. So their density is high. However, when surfactants are there, they displace water molecules.

@@NonstopNeuron yeess... Its clear... Thank you so much ❤️
wow nice
Excellent
Make more and more video's sirr great knowledge sirr
Sure I will
fantastic thank you
Superb
It's a very nice and helpful leatures.
Many many thanks
insane brœ I love u
Thank you bro
Welcome
Could you please make video on surface tension, pattern of dissolution and how pore former works.
There is no dedicated video but videos "Phospholipids in water" and "membrane proteins" might help. Search for these title in our channel. I hope that gives you some idea.
Best video I have seen❤❤❤
Thank you
Thanks to much
Most welcome
thank you
🙏🏻 thank you
Geee made it look easy🎉😂
thank you bhai! 10 min a exam hai mera bacha lia tune
Thnk u so mch sir🙏
welcome
omg nice
Thanks sir
Thanks
Welcome
Oh my God!!!! 🤯❤️🙌
Great!
can u please explain what's bulk means?
deep in the water.
@@NonstopNeuron thanks sm
Nice
Thanks
vese channel ke nam se ek que aya ki
does no of neuron increases in adult??
To my knowledge they don't
I still don't get it ☹️☹️☹️

Yes that makes sense 👍👍
