Thank you very much, I just clicked on all the other intermolecular forces videos on KZfaq and feel so tired and bored. Then I found your video, very helpful and easy to understand! Thank you one more time legend :D

According to the vapor pressure/ boiling temp graph, as vapor pressure goes up, boiling point goes up. I am confused how the molecules with stronger IMF have a higher boiling point but a lower Vapor pressure according to this graph? Time in video is around 26:30 onward
@chadmcallister34094 ай бұрын
Sorry Nick, I can see the source of your confusion. The graph shows a plot of vapor pressure vs temperature for a single substance. I provided it simply to give a more thorough definition of boiling point as the boiling point of a substance is the temperature at which its vapor pressure is equal to the atmospheric temperature. But note that it is just temperature that is plotted on the x-axis, not the boiling temperature. While we can deduce the boiling temperature from the graph, the x-axis is just temperature. The key though is that this graph just shows a single substance. If I were to plot the vapor pressure curves of multiple substances on the same plot, what you would see is that substances with lower IMFs would be left-shifted on the graph, and substances with higher IMFs would be right-shifted. There is a great plot demonstrating precisely this about half way down the page at the following link:wisc.pb.unizin.org/minimisgenchem/chapter/vapor-pressure-m10q3/ It plots the vapor pressure curves for 4 different substances. The one with the highest IMFs (ethylene glycol) has its curve furthest right from which you would determine it has the highest boiling point of the 4 substances. Hope this helps!

@user-bm2pn4rk4m Жыл бұрын
Can you break down how you found the molecular weight
@ChadsPrep Жыл бұрын
Is this about a particular time in the video? We find the molecular weight by adding together the molecular weight of each atom in the molecule from the periodic table

Sir why you are saying that the things which we cook at the top of mountain takes a greater time to cook as at the top the atm is also lower and so we also need low temperature to cook it so why it should takes a long time to be cook proper???
@ChadsPrep7 ай бұрын
Yes the water you are cooking food in will reach boiling point at a lower temperature, but, it is not the process of boiling the water that cooks the food but the process of transferring energy into the food molecules... so once the water boils it cannot get any hotter or else it evaporates, therefore the lower temperature means it takes longer to transfer sufficient energy to the food molecules to cook them
@user-vl1bk9jh4h7 ай бұрын
Mean that the sea level atm will be our standard atm and the vapour pressure of the things at sea level will also be standard so if we cook or boil food or water anywhere except sea level then we have to cook or boil it for longer time ?????

@@ChadsPrep sir you said that in case of LDFs electrons in an atom get freeze / stopped suddenly at one side due to which a dipole is induced in a nearby atom facing it . Sir it possible that electrons stopped moving suddenly?
@ChadsPrep7 ай бұрын
It is a temporary dipole - when I said "freeze" I did not mean that the electrons stop moving completely, more that they hover around that spot. The only way to 'stop' a paticle is to remove all of its energy.
