Incredibly helpful~ especially at my old age. I don't know if I learned and forgot all this or I just never understood it. But I understand it better now. However, I did not understand "the size of the degree". I do understand degrees in terms of things like angles, or diameters or in essence everything is measured relative to it's place in a perfect 360* circle. But this is not that. So my next study is 'degrees'. It kinda makes me wonder though when you talk about them 'making things up'. I did understand that. You have to designate 'starting points'. But then when you mentioned the match trick, and moving a pound by 1* degree...it got me to wondering, like the chicken and egg riddle, did the heat come first or the degree relative to how they were initially named or measured. Like I said, more study is in order, for me at least. But this was extremely helpful. You do a great job as a teacher~!
Always love your vids......i've told all rhe newbies at the Co. to watch your stuff.....I like watching on the commute really helps to get my head in the game in the morning.....thanks and keep em coming!!
Molecules can move (translational) and vibrate at the same time as related to spectra, outside the scope of this course. Friction really isn't relevant except between solids. The simple answer is thinking as elastic collisions (like billiard balls) and if inelastic (gas molecules slowing down enough) at the saturation temp & pressure start sticking together and form the liquid phase. You are moving into science of Thermodynamics here.
You said that the temperature of a swimming pool is different than that of “air” because the swimming pool has more “stuff” in it? Ok, then, what about humidity? That’s “air” combined with the “stuff” from the swimming pool! 🧐 What is the point of calling something “air” if not also taking into consideration it’s humidity level? 78° feels fine in low humidity but 78° at 90% humidity yuck 🥵

Does temperature only measure the average velocity?
What about frictions between molecules if there is any?
Do molecules move or they only vibrate?

Thank you.
So is a calorie the same as a BTU?
They are both units of measurement for heat. But they are not the same thing.
Heat moves from a greater to a lesser.
Temperature is the average of all the Kinetic Energies of individual molecules or dimers in a fluid.
The depth of this instructor is above anyone I have heard. I am a four year chemist.
I am fucking lost lmao I need to watch this 1000 more times
Don’t do that... it’s too many times, it will take too long and your family will leave you
I have

I didn't hear him say that. I heard him say that the water *feels* different than air at the same temp.
Why don’t the U.S. use Celsius like the rest of the world 😂
BC fuck everybody else! lmao
What u listening to?
Actually there is a point in which heat can no longer rise. It's called the Planck temperature lol.
Man!!!!!!!
Do you ever breathe between sentences ?

Kinda makes him sound like a stoner but maybe that's where I relate?
Press K key to pause and absorb the material. J to go back a few seconds for a repeat or L to jump ahead~!
@@HVACS Ah ha! Now you'll have to commit yourself to a video on "time"; no worries though, you won't have to make it on time, ha ha.
