You are an amazing … You are an amazing teacher!! Thank you so much! Been trying to read and understand this stuff for two days now and I watch one of your videos and Boom! I got it…Just want to say THANKS!!! =D
From the video, … From the video, right at the end: increased pressure causing a gas to go to a liquid, is exactly what goes on in a pressure cooker. Water stays liquid up to about 250° Fahrenheit, maybe 125°C .
phase bndry btwn … phase bndry btwn liq and sol is near vertical for H20. M.P. depression through pressure is minimal. Skating is NOT due to pressure-induced melting of ice .. complete bunkum. Read up on “theory of skating is “all wet”

it … to sconz ;
it doesnt take less change of energy or heat to go from solid to liquid . this diagram shows the opposite . follow this tow points and you will know ( 0c,1atm) and (-2c,7atm) . i hope its helpful
Thank you so much. … Thank you so much. I guess I’m like the fifty millionth person to say this, but this was awfully helpful. What program did you use to show this?
yeah because water … yeah because water is unusal as the denisty of the ice is less than the water this means that the molecules of the water are further a part !!!
did u get it ?!?!
think of it the other way when u apply pressure to the ice (molecules further apart) it will liquify (molecules are close to each other !!!!
did u get it ?!!! this explains why u get -ve slope for the melting point curve.
for other substances when freezes the molecules will condense more !!
hope I helped
I dont get why it … I dont get why it takes less and less heat to change water from a solid to a liquid the more pressure you put on it. You would think it would be the other way around.
Water ice does … Water ice does sublimate at freezing.
If you leave a tray of ice cubes in your freezer for a long time they will shrink.
This is also how freeze drying works, you freeze something at low pressure and the water sublimates out.

thank youuuuu.. God …
thank youuuuu.. God bless you
Wish he were my …
Wish he were my chem prof..he calls a molecule as guy check 5:05..its funny
A question arose …
A question arose from watching this video: What “heat” (J/g) is required to go from a solid to gas?
Haha the liquid …
Haha the liquid molecules are touching e/o and rubbing up against e/o. lmao loved the vid
The word for …
The word for reverse sublimation is deposition. Thanks for the video, It was very helpful.

“Sublimation” of …
“Sublimation” of ice cubes is probably caused by your freezer’s frost-free mechanism.
Agree about the freeze drying, though.
Lol I honestly …
Lol I honestly don’t learn a thing of useful information at my school. school I just watch these kinds of videos on Youtube all day.
thank you so much …
thank you so much for teaching me everything i don’t learn in class!
Its DEPOSITION that …
Its DEPOSITION that you are looking for SAL. :]
Great video! I …
Hopefully I’ll be able to pass my test now lol
Great video! I understand it now!!!

can u please post …
can u please post another video for the binary phase diagram ???!!!

solid condensation …
solid condensation I think

i think its because water expands as it cools down
