    The graph of pressure P and \[\left( \frac{1}{Volume,(V)} \right)\]of1 mole of an ideal gas at constant temperature is

    A)

    B)

    C)

    D)

    Correct Answer: B

    Solution :

    From gas equation \[PV=RT=\text{constant}\] where P is pressure, V is volume, JR is gas constant and 7 is temperature \[\therefore \]  \[P=\frac{RT}{V}\]                                           ?(i) Equation of straight line is \[y=mx+c\]                                         ?(ii) where m is slope and c is constant. Comparing Eqs. (i) and (ii), we get c = 0, hence it is a straight line with positive slope, which passes through origin.
