      Mujhe bhi yehi lga bcz Maine 2-3 days pehle hi revise Kiya tha ye ch usme *adsorption directly proportional to critical temp* Diya tha
      🙂Not inconvenience but convenient way to cover and revise whole ch I'm minimum time😎

      Sir, Topics like electrochemistry, chemical kinetics, solution(liquid state), Coordination compounds etc. One thing which is very unique about this channel is the solutions of past year questions of IITJEE. There are myriad of channels on youtube which focus on theory portion but they forget about equally important part which is problem solving and then I luckily stumbled upon your channel. :)

    Sir jee advanced 2017 question of surface property has some corrections- sir statement 1 is correct as higher the critical temperature more is the adsorption and here the critical temperature of ethane is more than nitrogen. Also the statement 2 is wrong as emulsion includes liquid as both dispersion phase and medium, but in given statement gas is given as dispersion medium. But above all these things thank you for all these PYQs videos.😊

    As critical temp. Increases it is more difficult to break adsorption , so extent of adsorbtion also increase

      @sapnasharma2823 3 года назад

      Correct but I have a confusion i.e we have two types of adsorption one which decreases with temperature and the other which increases with temperature , then how can we say that whether the situation is having chemical adsorption or physical adsorption and accordingly we can answer
