Excellent. So simple and very well depicted. I remember studying this during my chem engineering course and always struggled with the concept of "vapour pressure". This a SURFACE PHENOMENON (for example, cooling towers works according to this type of phenomena but in a different way), not an BULK one (such as boiling that you also explained very well) There is something that I appreciate very much about these videos and is its DURATION. Because if you make a 30 min video explaining a particular topic with ecuations, examples and so on, most people end up more confused Nice job man! Greetings from a "country" called Argentina
Thanks so much ACopp. I like your point about surface vs bulk phenomena, and in fact it has given me an idea - vapour pressures of immiscible mixtures…. These are additive which is different to miscible mixtures where the vapour pressure is intermediate. I wonder if there is a cool way to show the difference when you have one phase settling on top and exerting its own vapour pressure, compared to that same mixture under rapid agitation exerting the sum is the two vapour pressures…. Love to Argentina (I have a friend who is equally sarcastic about the place, but the people seem fantastic!)
@@ProcesswithPat haha! really?...it’s not so difficult to make jokes about Argentina, isn’t it? 😆...but yeah, there are still some decent people It’s a very interesting idea to see what happens experimentally with immiscible substances. Or partially miscible ones like phenol-water. With your style of explaining and the editing, I reckon it would be much more understandable as things start to get a bit more complex with more substances
Chemeng student here, I’m a little bit confused. I thought the reason that liquid evaporates at toom temperature is because the fugacity of the component in the liquid (P*i times xi) is greater than in the atmosphere (P times yi)
