  • hydrogen*

    

  • why do hydrogan bonds hold water together in the liquid phase but not the gaseous phase?

  • @sapphiremusic1993 In steam/ vapour, water molecules are too far away from 1 another. Hydrogen bond weakens as the water molecules go further apart so it has effectively no effects to the water molecules when they are in gaseous state.

  • This was a lot of help man thank God for YouTube and people like you. I wish you were my chemistry teacher keep the. Videos coming.

  • Mr. Andersen, I'm taking honors biology in asia, we use the same text book as you. Thanks you help a lot man!

  • WUAU, I TOOK ME LESS THAN 30 SECS TO SUSCRIBE TO THIS GUY!

  • However, (no room to say this below) I really think this was a great youtube and tweeted it to my son who was asking questions about why water has such unusual properties. :)

  • Not sure U can completely equate transpiration with capillary action. Plants do make use of the capillary action of water, but also it's cohesive properties when - as you so clearly explained - water molecules evaporate from the leaves & cause a negative pressure at the top of the xylem. As the water molecules move up they all "stick together" to give a continuous column of water- cohesion. In the case of thin tubes there is little evaporation just cohesion- water to water and water to tube

  • what do you think about dr. myotos "the effect of thoughts on water" experiment? also known as the rice experiment: if you label 2 jars of water and label one positive thing on one (i love you, thank you, beautiful, wonderfull, happiness) and one negative thing on the other, after a few weeks the microscopic structure of the ice flakes change drastically, including hue... just check it out please and get back,to me even if u,thimk its crazy

  • that helps a lot

  • Pro.

  • @FreeKicksPFC, i believe its because as the temperature drops, so does its kinetic energy. Same as when the temperature increases and water boils, you can notice the particles moving around and going crazy because of great amounts of kinetic energy. Ps. Hope it helps.

  • watched the whole thing kept repeating parts but why at the end does the water slow molecules slow down because they turn to ice???!?!?!!!????

  • This was actually very well done. All I can say is that it might be worth focusing a little bit more on the properties, such as cohesion. I know you brushed them, but it might be worth making a video specifically explaining these properties, why and how they work. :) Just saying, but this was very well done, you spoke clearly and were easy to understand, and explained your illustrations well.

  • everything my teacher talked about in my marine class thanks, very helpful

  • My biology teacher showed this to us in class..

  • MIIIIIIIIIIIIIIIIISTTERRRRRRRR­RRRRRRRRRRRRRRR! AAAAAANNNDEERRRRRRSOOOOOOON!..­............AAANNNDEERRRRSOOOO­OON.....

  • you basically just wrote my essay for me dude... you're a legend!

  • Awesome job! The visuals are so helpful and you go at a perfect pace. Keep doing what you're doing! :)

  • your the best

  • im taking bio in community college.... and u seriously mention everything we talk about ! thanks dude!

  • @SamanthaaSays im taking biology in highschool andi just finished my homework

  • Great video, thanks for posting.

  • my teacher assigned u to me...does that make sense

  • You are very helpful!! Come lecture my class!

  • THANKYOU SO MUCH MR. ANDERSEN, you pretty much got me an (A) in chemistry. You rock!

  • Thanks! I set up a playlist to exercise to...Your a great teacher~

  • I can see why you like that picture ;)

    Buc Double pointed it out!

  • can you please be my teacher

  • omg! i think i love you! you made it so easy to understand thank u , if i would have never came across this video i wouldnt have understood any of this.

  • I don't understand why this doesn't have more views, it helped me so much. I have my mocks tomorrow and I'm sure I won't fail it because of water properties! :D

  • Your white space issue seems to have reached a whole new level :)

  • Great video! Man I really appreciate your sharing of knowledge!
