The amount of heat energy required to convert the liquid into its vapor form is called enthalpy of vaporization.
00:08
This and the normal boiling point t can be calculated by plotting a graph between the logarithm of p on y axis and inverse of temperature on x axis.
00:21
So if you look at the graph, it is long p on y axis and 1 by t or we can write 1 by kelvin on the y axis.
00:34
So the units on y axis are 1, 2, 3, 4, 5, 6, 7, so on.
00:43
And on the x -axis are 0 .002, 0 .004, 0 .006.
00:52
And we need the graph at 0 .012, 0 .14, and so on.
01:01
So when we plot the graph, we get the values or the declining curve.
01:07
This way.
01:09
So from this we can say that y is equal to minus 711 .98x plus 15 .833 is the value obtained from the graph.
01:23
So based on this value let us find out delta h of vaporization.
01:29
In the slope m is equal to minus delta h vaporization by r...
