In the diagram as shown, find parameters representing `x` and `y` axes and also parameter `Z`, if `Z_(1) = Z_(2), Z_(3) = Z_(4)` and `Z_(2) gt Z_(3) :`

Options

A. Volume, pressure and temperature
B. Temperature, volume and pressure, it is only possible option
C. Temperature, pressure and volume, it is only possible option.
D. Both (b) and (c )

Answer

D

Explanation

d. If `x` and `y` axes are represented by volume and pressure respectively, and since `P prop (1)/(V)`, then parameter temperature `(Z)` cannot be represented by a straight line passing through origin. Option `(a)` is wrong. If pressure is constant `V prop T` and a graph between `V` and `T` represented by a straight line passing through origin. Further `(V)/(T) = (nR)/(P)` or slope `((V)/(T)) prop (1)/(P)`. But (slope of `Z_(1) Z_(2) lt` (slope of `Z_(3) Z_(4))`. So (pressure) `Z_(2) gt` (Pressure `Z_(3) Z_(4))`. so (Pressure) `Z_(2) gt` (pressure) `Z_(3)` and `Z_(1) = Z_(2) & Z_(3) = Z_(4)`. So option `(b)` is correct For similar arguments, option `(c )` is also correct
