Here in India its beginning of Monsoon season and Relative humidity is around 80%. Now i know why it feels Sticky/Muddy these days. Amazing Explanation! Thanks so much! :) :)
Thank you so much, I remember watching several videos around 2 years back without fully understanding the subject, the visual guides were very helpful to understand it, thank you.
Nice video. I think the concept could be taught alternatively using sponges of different sizes. A large sponge would be hot air while a small sponge would be cold air. You can pour the same amount of water into each sponge and show how the small one reaches 100% relative humidity first and starts leaking water back out.
Nice! What I appreciate is that you seem careful with your words and don't say the common (and incorrect) how much water the air can "hold". The air doesn't hold the water vapor; the water vapor exists in the vapor state in the air. And in theory, even if there were no air at all, those same 15 grams would exist per cubic meter at 17 C. It's all about equilibrium between the liquid and gaseous state. It just goes to show that one can teach a concept in a simplified manner without being grossly misleading 👍👍
Thank you! That is the challenge I always face with my young audience. I remade this video about 4 times to be sure my words wouldn't set my students up for later misconceptions.
Thanks for explaining. Ya know ive always struggled in my car when the windows fog up on the inside for exactly what I should do to unfog them. On the practical side what do we do? On a hot day when you have the AC on blast, the windows fog. On a cold wintery wet day, with heat on, it fogs. how do you know what to do to unfog the window? heat? cold? open windows? feel i always try everything and never know what it was that worked.
This is a super practical question! I love it. A few things are in play here. First of all you have to figure out if the fog/condensationis on the inside or the outside of the window. On a hot and humid day often the windows will fog on the outside because the humid and hot air is being cooled and condenses as it hits the outside of the cool windshield. You can check and partly fix this by turning the windsheild wipers on time every now and then. If this is what is happening try turning your ac to a setting other than defrost (blowing on the windshield) so that the windshield itself isn't so cold. That will reduce the condensation. On a cold and wet day I often get condensation on the inside of the window either from my humid breath or from water evaporating off my wet shoes and clothes as the heat dries me out (and transferres that water to the air in the car). Then the humid air condenses on the inside of the cold windshield. The solution to this is to crack the window so some of the moisture can escape and turn your heat on the defrost setting so that at least some of the moisture is being dried off the inside of the windshield and the windshield is warmed. When you turn your heater/ac to defrost (blowing on the windshield) it typically kicks on your ac system so that it begins removing moisture from the system. Remember the key is to try to engineer things to as to avoid moist and humid air from hitting a cold surface. That is when you get the fog.
Wow, that's so weird, the old link to the video is gone now, and I can't reply to your comment you made to me on that video, did you take down the video and make a new one? because that would explain it.
I feel like I have always had to think longer to get it than other people - sort of one step behind if you know what I mean. But I love it when I figure something out. Stay curious my friend!
Very nice and good video, although I have one remark. When vapor water is turned into liquid water it is not called condensation (which is a perpetuated misused term) it is actually called liquefaction. Condensation occurs when vapor (or gaz) becomes directly solid without passing thru the liquid form. Just to say ... Thank you for the content and keep up the good work 👍
@@christopherdever5536 I'm gonna have to look this up because that is not my understanding. Directly from vapor to solid should be deposition, not condensation.
You, my friend, are a natural teacher. Your videos are reaching all types of students for different career fields. Keep up the great work.
Thanks for the positive feedback! I appreciate the encouragement. Cheers!

Happy to help! Thank you for your feedback!
This is the best explanation I've seen of these kind of hard to understand concepts. 👍
Thanks for the positive feedback!
Thank you so much. i hope you dont stop making these videos. you are an amazing teacher!!
Thank you, I will!

Glad it helped!
He explains it very good. Easy to follow and to understand!
Glad it was helpful!
Because of the metric system
Great video! Do more of these, please!
Thanks! Will do!
@@christopherdever5536 Great! I'll wait for them!
As an avgeek ive often heard ATC inform pilots of dew point. I never fully understood what it meant, now i do, thanks 👍
That's great to hear! Thanks for the feedback.

I've been refining this one and I think I did pull the old version.
@@christopherdever5536 ok.
I like how he explains it so easily so as people as dumb as me can understand. Maybe he once was as dumb as me

Wow! Didn't know that. So condensation is technically the opposite of sublimation!?
