The regions where each occurs for molecular nitrogen N 2 are shown in the figureNote that most conditions in the figure correspond to N 2 being a supercritical fluid.

Block B has a volume of 2L 2L 2L 8L 3 which is 4 times that of Block A. CV is also known as relative standard deviation and in general displays the size of a standard deviation to its mean. The temperature change produced during a JouleThomson expansion is quantified by the JouleThomson coefficient This coefficient may be either positive corresponding to cooling or negative heating.
Try solving the following questions for better understanding of the concepts. The cross-sectional area of Block A is L 2L 2L 2 while that of Block B is 2L 2L 4L 2. The change in area is proportional to the area.
Hence 5670 x 4 is the middle term of the expansion x 3 8. Here x denotes the variable and a and b are the coefficients of the equation. The coefficient of variation as read in the introduction is also recognised as relative standard deviation.
