Hello students, in this question we will draw the phase diagram of water.
00:06
We will level the areas and regions where the phases, that is solid liquid and gases occur.
00:11
We need also to mention the triplet point and critical point and to discuss it.
00:16
Let's do it.
00:19
And here we can see the phase diagram of water.
00:24
First let's try to understand this.
00:26
This particular diagram is against temperature on the temperature on the temperature.
00:31
The x -axis and the pressure on the y -axis.
00:35
In this you can see this curve, this curve is once on its left side is circling the solid and on the right side it is in association with the liquid.
00:48
So, the curve that suppresses the solid in the liquid, this is the melting curve.
00:54
On this side, melting occurs, on this side, fusion occurs.
01:00
And if we extend this curve here on the x -axis further, we can see.
01:04
See when the pressure is zero atmospheric pressure, this curve is there and this is reaching to the maxima of it and this area belongs to the gas.
01:16
It means this point, this curve is the sublimation curve because it is bifurcating or dividing the solid to that of the gas.
01:26
Similarly, you can see this curve, the curve from this portion up to this portion.
01:32
This is separating the gas.
01:34
And the liquid.
01:36
So, this curve is, you can say, is a boiling or condensation curve and the process is condensation and the evaporation is going on.
01:51
The phase diagram of the water has got some special features and this special features has to be noted and it should be discussed first.
02:02
And the first point of this is the phase diagram of water.
02:11
The slope of the line between the solid and the liquid.
02:16
We are talking about this line, solid and liquid line.
02:20
This curve is negative.
02:24
And the curve is negative because water as liquid is more denser than its solid, that is ice, and it floats on it...
