omg thank u so much!!! I saw this question during my olympiad prep and I was so confused cause this wasn't taught in high school but u explained it so easily!! I was almost gonna cry lol I couldn't find it in my book
for density, are we to approach it as like when density increases it's b/c the mass increased or b/c volume decreased? for example when you increase pressure of solid h20 and it enters liquid phase is that b/c there's more mass per area of volume (overall mass doesn't increase I believe?) or is it b/c there's now less volume? as always loving the videos!
The reason ice is less dense than liquid water is due to molecules spreading out into a crystal structure upon freezing which maximizes the number of hydrogen bonds formed. So the same number of molecules now spreads out into a slightly larger volume and hence a lower density. When higher pressure is applied to a substance it will tend to occupy a lower volume (we see the extreme of this for gases but to a much, much smaller extent also for solids and liquids). But if the conditions are very close to the solid-liquid line of equilibrium higher pressure could also lead to a phase change favoring whichever phase takes up a smaller volume (i.e. whichever is more dense). Hope this helps!
So Ive received this question twice on my exams and I always get it wrong and forget the answer but what is the ideal conditions for a gas? In terms of atm and temperature
Hi Kandace! It comes with videos tailored for the OAT and plenty of practice questions for the sciences (no reading comprehension presently) including quizzes following each video and 5 individual practice tests for each subject. You can see all the details here: courses.chadsprep.com/bundles/chads-dat-prep Happy Studying!

I’m new to the channel and WOW! This man just explained a 2 hour lecture in 14 minutes better than my professor, thank you goat!
Great to hear!
This is very helpful sir! been struggling to understand phase diagrams on physical pharmacy but now it's not that complicated, thank you so much!
You're welcome - Glad the channel is helping you!
@@ChadsPrep 教授.實驗時是否忽略低壓時空氣的存在?我看示範實驗時把放水的杯子放入抽真空罐中.再蓋上抽真空.裡面不是有空氣嗎?

You're very welcome - glad you found us!

Welcome!
Man, I love your teaching style w/the tradition white board. And your Christian-themed shirts are wholesome.
Glad you like it, JT!
Am new to this channel but now I really understand phase diagram
Welcome to the channel - Happy Studying!
Loved this! Very helpful
Glad to hear it!
🎉
Thank you teacher!
You're welcome!
Understood 😍😍 thank you
You're welcome!
The best i couldnt understnad this before
Awesome!
Love this was really helpful ❤
Excellent!

What abòut phase diagram for sulphur compounds or compounds that have allotropes ..how do they behave
So for melting and boiling point how do you know where the atmosphere Will be? (Is it usually a given?)
Can you clarify your question a little further when you say - where the atmosphere will be? Is this in reference to something said in the video?
Wowww.Wowww...best explaination
Excellent!
Thank you sir
You are welcome!
EXCELLENT
Thanks!

Does the OAT Prep package come with videos and practice questions?

@@ChadsPrep Good to know. Thanks!
@@kandacemesser9509 👍 👍 👍
What do you mean by ice is less dense than liquid water??? I don't understand sir???
If you put ice cubes in your glass - do they float?
@@ChadsPrepno sir .😶
Go get a glass of water, add the ice cubes, if they don't sink to the bottom, they float and are therefore less dense than liquid water
@@ChadsPrep He is using ice of T2O 💀
what a chad
Welcome to the channel.
Thank you so so much I was losing hope
Very welcome - don't give up!
😮understood
😀
What's the actual triple point of water? You failed to provide the number. Great presentation otherwise - thank you xx
That would be a temperature of 273.16 kelvins (0.01 °C) and a pressure of 611.73 pascals (0.006 atm)
دکتر جانی باشه؟!؟!
Happy Studying
