It will be weight fraction, since the x-axis (and hence the quantity we are conserving) is weight. When calculating phase fractions, we tend to conflate wt., at. and vol., when really we should be precise and say what we mean. Often people just talk of the 'fraction' f, to avoid this issue.
sir, for maximum solubility you dropped a vertical line onto X-axis from maximum solubility of alpha phase and calculated the distance from O.how is that distance different from the distance from Y-axis to point of maximum solubility of alpha? can you please explain me?
Great half an hour lesson you added to my knowledge. Thumbs up!!!!!!!!!!!!!!!!!!
these lectures saved me before my exam, thanks a lot.
Thank you Dr. Dye: you've taught an old dog some new tricks.
Thank you. This video is really usefull to learn.

Great lesson
The Doh! at 16:30. Huh. I thought I'd deleted that. I guess we all make mistakes. The important thing is to catch them before you submit the test!
I know I am quite off topic but do anybody know of a good place to stream newly released tv shows online ?
@Roman Callum I would suggest flixzone. You can find it by googling :)
@Maison Cayson Yea, I have been using FlixZone for since march myself :)
@Maison Cayson Thank you, signed up and it seems like a nice service :D Appreciate it !!
@Roman Callum no problem :D

I also got confussed. I think it will be good to say that the measure of 3,2 is from 0 to 5, and not to from 0 to the vertical line he draw :)
sorry sorry i misunderstood. i got it. thank you for such a great explanation.
13:45 that was 1.9% wt instead of 1.6% wt. And that will give you 616 grad C instead of 608
