Me:*spending all my time on roblox*
My dad:you should do some more academic work.
Me:fineee i will see one of those biology courses on yt.
Me:finds this series,and slowly starting to love it also watching all of this guy s vids.
Me:realises these vids are for ppl in college and i am legit ten years old.
Did the meaning of cohesion and adhesion change?
Stop. Stop, stop, stoppity stop. At 9 minutes: 'If all the ice at the North Pole would sink, water levels would rise, and there’d be no land’ (paraphrased). Um…do that experiment with the ice cube again. Look at the water level before and after. Oh, look, it goes up! Now wait for the ice to melt. Did the water level go up more? No! Ice floating on water displaces its own mass of water. It’s called buoyancy. I know you knew this already, and just forgot for a moment. Might want to add a text comment on the video, though, or you’re gonna confuse a lot of people.
why does he sound the same no matter how fast you put the playback speed to lmao
How did he do that like splitting up things for the video?
"which is why we put hot water bottles in our bed and cuddle with them when we're lonely" smiles sadly what an epic mood
Anybody else want to see Hank as Dr. Who?
Damn that book isn't available on amazon
He could just be saying words and I would never know
Could you please do a crash course on the science of smoking? Thank uu!
Why does capillary action increase when the diameter of the vessel becomes thinner?
who else is here cramming for the AP tomorrow?
Everytime Hank touches his glasses take a drink…..lol
so salt dissolves because it bonds with water molecules better than water molecules to themselves?
when you are a weak electrolyte in a world of hydrogen bonds
so cohesion is possible because water molecules are more electrically attracted to each other than to the surface molecules,
and adhesion is possible because water molecules are more electrically attracted to the surface than each other?
"penetrate and come into it"
This is so wonderful and creative for someone who is a classical pianist, thanks for making it fun.
Isn’t hydrogen bond the stronger bond than dispersion forces. So how do we call it a weak bond?
2020 😊
They are bonding, that’s not social distancing 😳 (if my science teacher sees this that was a joke)
helo
*HYDROGEN BONDS*
Dude you are an amazing teacher!
