Sir I think this was the best video on RU-vid on the concept Diffusion and Osmosis it cleared all my doubts and I had that question on mind that diffusion and Osmosis occurs in which molecules, and now its clear thank you sir
@@NAJAMACADEMYSir How do you create these videos I mean any website or app for designing it in such amazing way if you can please tell me would be really thankful for your help
Thank you Soo much sir , tomorrow is my presentation..I searched and watched every video but my concept was not clear..and then I found your video.. everything is cleared in simple words again thanks you so much ❤️👍
Sir diffusion does take place in solids, what if we leave chalk on blackboard for 20 - 30 days, there will be residue,its even given in my book ( ncert ) even though its a very very slow process dosent mean its not there
Sir but osmosis means movement of substance from region of lower concentration to the region of higer concentration. Diffusion means movement of substance from region of higher concentration to the region of lower concentration
Diffusion can occur in solids but it takes a very, very long time. For example, if you write on a blackboard with chalk and leave it as such for a few weeks, it is very difficult to get the chalk off the board. So, some amount of it has diffused. For things to completely diffuse, it can take centuries, so we don't usually say that solids can diffused. Hope this helps :)
solids diffuse at a very slow rate, the reason is because the molecules only vibrate and do not move freely like in solids and gases. that's why we say solids don't diffuse, gases and liquids diffuse in minutes or even seconds because of the kinetic energy in their particles and their weak intermolecular attraction allowing them to move quickly.
All had taught me about this chapter,but I don't understand.After watching this video,I have understood the all thing . This video will be very helpful to children if they have any doubt.😊
Sir please make a video for cytoplasm,nucleaus,endoplasmic reticulam (er) and Golgi apparatus. I am not saying you to make it separately for each organelle. You can just in one shot
As u said osmosis is concern with movement of water molecules only.then how absorbtion of digested food through intestine is osmosis? Is n't it diffusion?
Doubt-sir if there is high concentration outside the cell and low concentration inside the cell then water moved inside the cell will be more than water moved outside,but my doubt is that why water will move outside even if it is less than outside it should not move if there is high concentration putside the cell
I have a question.You said that diffusion only occurs in gases and liquids, so why sugar as a solid substance creates diffusion when putting it in tea?
Excellent Question!!! 🤗🤗🤗🤗🤗 Firstly, sugar dissolve in water due to its polar nature. Once, it is dissolved in the water... It will than diffuse in the water. So the sequence is... Dissolving and Diffusing... Thanks!!! 🙌🙌❤
1.Does Helium baloon goes upwards because of diffusion?? Helium is the lightest gas, so being lighter than atmosphere it flys upwards. 2. Is digestion an example of osmosis?? During digestion obviously the digested food passes to circulation, not only water. But osmosis means only passing of water. Digested food goes to circulation through passive or, active process. During passive process, some foods move to circulation through diffusion.. Correct me, if I'm wrong.
HI DURING THE PROCESS PF RESPIRATION T HIS PROCESS HELPS IN DIFFUSING THE CARBON DIOXIDE GAS OUT THROUGH THE CELL MEMBRANE INTO THE BLOOD . WHAT IS THAT MEAN ? DIFFUSE OR PRESSURE DIFFERENCE . ???
