I like your style, explanation, presentation. Only if I had a teacher like you in my earliest school years.
Less dense warm air rises cold air sinks
Who else is downing it for homework
the food coloring just shows how the warm and cold water sink or float
me
Me
me
Why else would I be here
Thank you SO much... I've been TRYING to describe this concept to my dear wife for YEARS! I finally TH-cam searched and "there you were"! Thanks, again!
Я здесь всего лишь для того, чтобы сделать домашку по английскому
Thank you so much for taking the time to make this video. It helped my son greatly with his science report.
Тоже стало интересно что это за ссылка в учебнике инглиша?
не, это наше дз)
Прикольно конечно ссылку вводить вручную из учебника -_-
Лайк кто из Беларуси
it‘s a vivid demonstration. thank u ,Jared
I thought that this was amazing! My science teacher showed us this in class and I loved it! It looks like jello...
+Kiera Tyler (Skulette8) So happy to hear these are being used in your classroom, check out our FunScienceDemos channel for more videos on a wide array of science topics. And show your teacher too!
Кто пришел делать английский язык?
Thank you for all your help
men thanks for posting it, very intresting, I was next to my stove and i wondered if water will react the same..
Where did you get the tub (specifically). Trying to find tall, clear tubs like that one.
Didn't know that - that water density varies so significantly. Thought it was practically incompressible. 'll be interesting to see the same experiment with water at 1°, 2° and 3° C.
Thank you George you made things even clearer !!
Khalid Hassan Khan eh la name is Jared dud
Thanks for this experiment
Well done. :) Helped me understand where my A/C was failing during this heat wave.
Sarah F Glad we could help! Science is so cool. Thanks for your input!
Thank you, awesome video to explain and understand.
You should try using a glass bottle or glass container, that can stand on the bottom, for the warm water so that you can more accurately see the warm water rise to the top.
This is a great experiment! :-) Thank you.
Wow that is an amazing explanation 😊👏🏽👏🏽
Thanks. That will really help on my science test 😀
+Spud bud We are glad that you found this helpful! Please look into our other TH-cam channel FunScienceDemos for more video demonstrations!
Я оставил свой след в истории, перейдя по ссылке из учебника по английскому...

PS как я понял суть эксперимента показать, что холод опускается вниз, а тепло уходит вверх)
I remember doing something like this in my science class.
This is beautiful!
Thank you for helping me cause of this!
So, if you fart outside, no one’s gonna know, since the fart will fly to space?
Кто тоже делает тут дз по инглишу 9 класс?
Experimental learning is always best. and yess this one I will never forget👍👍👍
Do you need a large container like that or any container can work ?
How do you know the red dye molecules aren't less dense than water molecules, and blue dye molecules heavier? Did you reverse the colors between the temperatures to check?
I was eating menudo and wondered how long it would take for my bowl of soup to cool. Thank you
Thank you for helping my son.
Can Someone tell me what is dependent and independent variable in this experiment?????
It's weird how I could never understand that nor notice it.Thank you for your explanation.Now i understand.😁
u made an acidental link
What is the relationship between density gravity and temperature
great experiment
Thank you this helped
Thank you, sir
Can this also be for a experiment?
I tried recreating this experiment but it doesn't seem to work. The hot water won't be floating in the manner shown in the video unless it is of a lower density than the water in the tank. Maybe the water in the tank contains salt/sugar. I'm pretty sure the set up is skewed in a way to make the result more "dramatic"/pronounced
who else is here cause the teacher said that there was no zoom call?
lol me
Beautiful
This simple principle "warm air rises, cold air sinks" is going to change the world soon! I know how!!!
Can someone tell me what type of heat it created?
can some one tell me what is the controled variable is in this experiment
this is a demonstration, not an experiment. he is showing a concept, not trying to obtain results.
What is the energy transfer
sir i want to know as you tell me that cold water more dense does it mean have more upthrust force is more density mean more upthrust force??? is cold water easy to swim???
why the colour only flows at top container???
there is a link to your video in the Belarusian English student's book
George loved you man. What an experiment :)
Utkarsh Mishra eh his name is Jared
Is using food colouring necessary or can we use can color
Please tell me cuz I have an assignment for this
densities based on temperature
It's cool
thank you guys
+mohamed hayatu So happy you liked it, check out FunScienceDemos our other TH-cam channel for more videos on a variety of topics!
I love how he says not to burn yourself and then he pours hot water on himself😁😆
tell the method
Keesom Interaction
if you heated a large pot of water to 90 degrees C and dropped an ice cube in the hot water would the ice cube sink because it is more dense than the hot water?
Ice has a lower density than liquid water is the cold water which sink, not the ice. So in your example, the ice cube will melt and if it's enough ice (and can melt and mantain a low temperature) it will sink (the cold water, not the ice cube).
Solid water has a lower density than liquid water because the hydrogen bonds form a cristal structure that is larger (occupies more volume) when you freeze water it's volume is larger in solid state than in liquid state (aprox. 11% larger), and density is: mass/volume, since the mass doesn't change and the volume is larger in solid state, ice cubes have lower density than liquid water ^^
My college chem textbook says ice will sink in water if the water is hotter than 90 degrees C (assuming the ice doesnt melt)
If you hold your finger over the red bottle and put it at the bottom - use glass instead of plastic so it will stay down! - you can actually see the red hot water rise instead of just sitting at the top. What you are showing is not actually convection, because one can't see the flow patterns. You are just showing that hot water is less dense than cold water.
So why do people mount garage heaters on the ceiling?
I have a question that
Food colouring is necessary
Plzz reply I need it for my project
Can we use water colour?
great, how about a chemtrails test?
So why don't they mix?
Hi, bro Can you tell me what is dependent and independent variable in your experiment?????
+Afnan Abid this is a demonstration rather than an experiment. an experiment requires a question to to be asked and then seeks to answer than question. however in this case we seek to observe the rising of less dense hotter particles then the independant variable is the heat source and the dependant variable is the density of the particles.
Thank you bro so much Jay-sen Phang
I'm thinking the indep var is the difference in temp between the water samples, and the dep is the location/relative position of the two diff masses. (How are they different? Temp. What is observed to see the effect of this difference? location in the pan.)
*9 класс вошёл в чат* ✌😎
Awsome
still don't get it but thanks!
So cold water is heavier (weighing more) than warm water of the same volume. Is this correct?
But mother nature of course is not that flat and boring. It is not a straight line but that is another story. Cold water may sink but ice floats. Well gosh I am sure there is even more than this. As you heat water in a container, the water that is getting warm is not exactly going to go and rise, there are all kinds of up and down motion in the water. Some warmer water may be actually be heavier than its lower temperature counterpart.
S
hot go up cold go down
Nice
How does hot air rises up and cold air goes down?
why cold waters density is lower than hot waters density?
Is it possible for me to use this video as a source? I'm currently debunking a popular video game theory that relates to water temperature. o_o
RadiusZero debunked it yet
nice
Right now as I type this, there are people on another comment telling me that "coldness" rises upwards. Ergo, putting cold metal balls in a wine glass will chill the entirety of the liquid in the glass.
TH-cam needs a facepalm emoticon
Rizzy Khaos This is actually because water in ice form is less dense than room temperature water (or liquid).
frick yeah
why is hot air/water less dense and why is cold air/water more dense?
+Rachel Isaacs The atoms and molecules in hot air/water are moving faster and that energy spreads them apart. In colder substances, the atoms compact, making them more dense. Another video you could check out is "Hot & Cold Water in a Straw" on our FunScienceDemos TH-cam Channel. Thank you for your question
George Mehler thanks man, you explained it cleary and nice experiment :D
why tho? why does the temperature effect the density?
The hotter the water the faster the molecules move. With this movement they use more space. You got less molecules per square cm, hence you have a lower density.
barty tholimule density is the idea that molecules are closely packed together. When temperature rises the molecules get more excited. These molecules are then no longer closely together,hence making the hot water less dense.
PV = nRT, explains everything
Сижу на уроке английского и смотрю твои видео 👍
What phenomenon does is demonstrate?
Would this work without gravity?
+Adamant Adam no
+Jay-sen Phang Why? Is this because of the differences in enegy density?
it's not to do with energy density (that is not really a thing because density = mass/volume). A warmer fluid is less dense than a cooler fluid. The cooler fluid is drawn down by gravity with greater force (force = mass * acceleration) as it is heavier. This displaces the warmer less dense fluid upwards. Without gravity the cooler fluid would not be heavier than the warmer fluid therefore no displacement would take place to cause your typical rising/falling convection current.
YES it would work
If you SOMEHOW managed to keep the water not exchange heat, the warm water would eventually gravitate above the cold water.
No, it won't work without gravity because gravity cause more force on heavier(mass) object and less on lighter object.you can see in water hot water have less density of particles due to high temperature and cold water have high due low temperature....so if there is no gravity then all particle will stay at there places and no one will go down unless other external force is not applied.
Whats the explanation of this?
Explanation at 2:00
The explanation is that ... there is something called convection currents happen in fluids .. which states that when water particles get hotter they become less dense and rise..at the same time cold ( more dense particles) replace them and move downwards... (HEAT ENERGY TRANSFER )
Warm water RISES & Cold Water SINKS - if the temperature is ABOVE 4°C,
Warm water SINKS & Cold water RISES - if the temperature is below 4°C
(that's why the fish swim on the bottom of a frozen lake in winter time).
to protect the underwater world :)
Water’s polarity overcomes the molecular motion at 4 degrees C. Water starts aligning its molecules in a crystal-like structure which is less than warmer.
Is it suitable for class10
YOU'D THINK SNOW WOULD BE ON THE BOTTOM OF THE MOUNTAINS AND THE WATER AT THE TOP
YO YO lolololol
The atmosphere is the medium, not water. The density of the water is uniform from top to bottom, so the temperature is the only differing factor. The atmosphere is made up of different gases with different densities, so there are more variables that come into play and we wind up with a different result.
water is incompressible in this situation... no convection
Cool😗
you look like william ryker from star trek
not really
If cold water sinks, why do ice cubes float?
Very cool and creative! It helped my daughter a LOT.
Watching this for school btw
What phenomenon does is demonstrate
So thats the reason why if I duck down in the shower the water feels cooler-
