Question
Pressure versus temperature graph of an ideal gas is as shown in figure.
Options
A.
B.
C.
D.
Solution
As PV = nRT m = ρV = constant or ρ α 1/V
PV = nRT m = ρV = P α ρ
A → B T = constant, pressure increases or volume decreases
B → C Volume is constant, V = constant
C → D P is decreases or volume increases [T = constant]
D → A Volume is constant V = with constant,
clearly option ′B′ is constant.
