Properties of Water | Hydrogen Bonding in Water | Biology | Biochemistry

Why is water essential for Life to exist on Earth? We are about 60% water - and there are some organisms that are as much as 90% water! What is so important about water? How does it support life?
In this video, we discuss the special properties of water that make it the “Solvent of Life.” Chief among these properties is the extensive Hydrogen Bonding between water molecules that make water an extremely cohesive liquid (the molecules stick together). Due to the extensive hydrogen bonding, water has some emergent properties that impact life on Earth in many ways. These include:
Cohesion
Adhesion
High surface tension
High specific heat
High heat of vaporization
Ice Floats (Ice is less dense as a solid than liquid water)
For each of these properties, we discuss how they impact living creatures on Earth.

About our instructor:
Kimberly Hatch Harrison received degrees in Biology and English Literature from Caltech before working in pharmaceuticals research, developing drugs for autoimmune disorders. She then continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time, accepting a position at an exclusive prep school, where she taught biology and chemistry for eight years. She is now the head writer and producer of Socratica Studios.

[@salifyanjimufwaume3019]

It is very helpful 👍,am impressed

[@lazytimewaster]

Why does this video make me feel so relaxed while covering such "hard" biology content?

[@ahmetziyaaktas9179]

Because she has such a brilliant voice tone! 🤓🤓🤓

[@period3hues]

Best biology video I've found! Way better than Crash Course. I love how clearly stated all of this information is. Great diagrams and sounds as well.

[@Cryssparks]

You covered all the main points from my biochemistry lecture, and in such a well spoken way. I love all of these videos so much! Excellent work. As a student focusing on molecular plant biology, I adore the greenhouse, nice shout out to transpiration.

[@ShortCakes]

Wow! You are a life saver. My Biology teacher is not so great at teaching and so many of us are failing. I study and read the chapter but her quizzes are always before teaching the material and so so in depth. This video was in depth and like reading my chapter but come to life. You have such a wonderful way of explaining. I am so grateful....thank you so much!

[@brianlipsey9883]

What an amazing teacher! It is a shame there is only 6 videos with this woman :(

[@teresahefner2957]

Thank you for making a complicated subject more simple to understand.

[@kainchinmanatad9016]

She looks like Lena Headey. Wonderful and so informative video. Kudos 👌👍✨

[@aragtz25]

Wow!!! So relaxing yet so informative ;)

[@itsReallyLou]

Beautifully done!

your examples makes me to understand this topic very well so keep it up !!!!!!!!!!!Thanks from south sudan

[@bobsmith8394]

The heck this video was so good much more detailed than crash course this video seems like it took a long time 2 make. It seriously is underrated. One of the best educational video i ever watched.

[@Socratica]

Thank you so much for your kind comment! We really do put a lot of love and attention into our videos. We will probably never be as big as Crash Course, but we do take our writing and editing videos really seriously, and hopefully they will stand the test of time. It's viewers like you that make our time and effort worthwhile!

[@john-rosskuzora272]

So amazing, loud and clear, well explained lecture. you've made it easier. looking forward to watch more of your videos. 💯👌

[@Misslayer99]

This is the loveliest most ethreal biology video I've ever seen. I've grown orchids for 20 years so the background is pretty awesome. Also no joke I used to have a pet Jesus lizard(aka basilisk lizard) and his name was Jesus(pronounced Hazeus) unfortunately when bred in captivity they're not able to run on the water.

[@stevenwoody6957]

Great Video!

You're so kind, thank you!!! 💜🦉 It *is* incredibly helpful of you share the videos you like with your friends and on social media, because we don't always show up in the search results on YT.

[@raghumalhotra3490]

One of the best videos i have ever seen related to science and its magic😀A totally different experience 💗

[@thegoodlydragon7452]

What happened to this series of lectures? Is it going to continue to other biochem topics?

[@sopheymont]

awesome. thanks a lot! you helped me with my homework!! great job, thank you so much. God bless!!

[@Socratica]

We're so happy to hear our video helped!! Good luck and keep us posted how you do!! :D

[@cassiemusongo8824]

This is beautiful. I am in university but this explanation is top notch

Can you do another one on protein please....

[@zahoben3980]

water is just... amazing

[@cydrickdones761]

Here for the module🙂

[@dkmemes3815]

11:26 They thought we wouldn’t notice the Assassin’s Creed Origins bird sound effects 🙄

[@iden4371]

Everyone here is saying that this is extremely helpful. I must not be very smart then, because I'm not grasping the information. Maybe I need to take a break and come back to it later so I can maybe better comprehend this.

[@hennabyrg9053]

A unique video with a relaxing voice! Fabulous thank you!!!!!

[@GuidetteExpert]

I never looked at frozen water as being a protection for the life inside the sea and for the life on top of the sea where animals can walk on it. For the purpose to walk away from such cold environment? Or even float on the ice away to a better climate?

[@rajeshbista5010]

you are amazing !1!1!

[@SevenDeMagnus]

Thanks again. Truly gifted with saintly voice and demeanor- the brain learns and absorbs better, your voice and overall look/presentation. If I may be deep scientist mode (yup I'm technically a scientist too, a kind of engineer) I guess because the brain and mind is relaxed via the cool, kind voice frequency and tone, it seems to resonate w/ the brain and thus the mind, making the brain work more efficiently to focus well. If this physics biology segment is in VR (it can be just static 3D, panning around could be a distraction), it'll even be more focused. See you in heaven, Kimberly. God bless, Revelation 21:4

[@livinginlanguages856]

Great teacher, great style. You do this charmingly and you manage to get so much into such a short video. Without cramming it in or going too fast. A real professional.

[@nightrain18]

How would it show when a nucleic acid interacts with water?

[@ahmetziyaaktas9179]

How well explained everything! Thank you so much. This is such a marvellous summary. 🤓💙

Cells in the human body can have lower or higher water concentration then 75% depending on what type of cell it is.
