The figure below shows the plot of `(PV)/(nT)` versus P for oxygen gas at two different temperatures

Read the following statements concerning the above curves:
(i) The dotted line comesponds to the ideal gas behaviour
(ii) `T_1gtT_2`
(iii) The value of `(PV)/(nT)` at the point where the curves meet on the y-axis is the same for all gases
Which of the above statement is true

Options

A. (i) only
B. (i) and () only
C. All of these
D. None of these

Answer

C

Explanation

(i) `(PV)/(nT)` = constant for dotted lines, i.e. behaves ideally.
(ii) At high temperature, deviation of the gas is less and at low temperature the deviation of gas is more i.e. `T_1 gt T_2`
(iii) Since, two curves intersect at dotted line, so the value of `(PV)/(nT)` at that point on the y-axis is same for all gases.
