All right, guys.
00:04
So for this question, you can refer to figure 9 .9 .19 of the book.
00:28
And it's page number 326.
00:35
All right.
00:36
So you draw a vertical line at 52 % weight of zinc.
00:42
Draw the horizontal lines at each of the temperatures in the problem until they cross the vertical line.
00:50
So at 1 ,000 degrees centigrade, we are in the liquid phase.
01:08
We are in liquid phase.
01:23
And thus, the fraction is, fraction is one.
01:36
So at 800 degrees, we are in beta phase.
01:54
We are in beta phase.
02:08
And the fraction is again one.
02:24
All right...
