Graham's Law of Diffusion | Theory & Problems | Tricks & Techniques | Jee-Mains, Adv | NEET | AIIMS Video
Hello Guys
Finally, Something very important for IIT-Jee and Medical from Gas Laws. Yes, if you are searching for a video about Graham's law of Diffusion or Effusion, then You are at right place with most suitable video. Ok, Guys
Lets Start...
This video deals with a great mathematical approach of Grahams law of Diffusion. Suitable practical examples are used for explaining diffusion and effusion which makes it quite interesting. Sufficient derivations along with cases are used in the lecture. Also, We have solved and explained some interesting problems inside the lecture.

Numerical Discussed in the Lecture:
Q.1 The Rates of diffusion of 235 UF6 and 238 UF6 can be represented by the ratio :
(a) 1.004 : 1 (b) 1.1 : 1 (c) 1.125 :1 (d) 1 : 1.25
Q.2 The relatives densities of O2 and CO2 are 16 and 22 resp. If 25 cm3 of CO2 diffuses out in 75 sec, what volume of Oxygen will effuse out in 96 sec under similar condition?
(a) 40 cm3 (b) 35 cm3 (c) 37.5 cm3 (d) 42.5 cm3
Q.3 One mole of N2 gas at 0.8 atm takes 38 sec to diffuse through a pinhole, while 1 mole of an unknown Fluoride of Xenon at 1.6 atm takes 57 sec to diffuse through the same hole. The molecular formula of the compound is:-
(a) XeF2(b) XeF4 (c) XeF6 (d) XeOF2
Q.4 A straight glass tube has to inlets x and y at two ends. The length of the tube is 200 cm. HCl gas through inlet x and NH3 gas through inlet y are allowed to enter the tube at the same time. White fumes first appear at a point P inside the tube. The distance of P from x is-
(a) 81.13 cm (b) 105 cm (c) 87.15 cm (d) 125 cm
Q.5 Two balloons are filled with equal moles of Hydrogen and Helium. Which balloon will contract if holes of same size are made in them?
(a) Hydrogen balloon (b) Helium balloons (c) Both will contract at same time (d) cant predict
Q.6 A cinema hall has equidistant rows 1 m apart. The length of the cinema hall is 287 m and it has 287 rows. From one side of the cinema hall, laughing gas (N2O) is released and from the other side weeping gas (C6H5COCH2Cl) is released. In which rows, viewers will be laughing and weeping simultaneously ?
(a) 187th row from N2O side
(b) 100th row from weeping gas side
(c) 150th row from weeping gas side
(d) 100th row from N2O side

About the Site 🌐
This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥
Origins of the Idea 🌱
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠
Challenges Faced 🤔
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍
Creating Truly Random Links 🛠️
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
About YouTube 📺
YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟
Content and Users 🎵
Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.
While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.
Monetization and Impact 🤑
YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.
As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
