Question

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.

Answer 1

Answer: (B)

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.
