Question

A plot of volume (V) versus temperature (T) for a gas at
constant pressure is a straight line passing through the
origin. The plots at different values of pressure are shown in
figure. Which of the following order of pressure is correct
for this gas?
(a) P₁ > P₂ > P₃ > P₄ (b) P₁ = P₂ = P₃ = P₄
(c) P₁ < P₂ < P₃ < P₄ (d) P₁ < P₂ = P₃ < P₄

Answer 1

$\huge\underline \mathfrak \blue{Answer}$

(c) P₁ < P₂ < P₃ < P₄

Answer 2

P₁ < P₂ < P₃ < P₄ is the correct option.

Explanation:

• According to the ideal gas equation, the product of the pressure and the volume of the gas is equal to the product of the number of moles of gas with the ideal gas constant and absolute temperature of the gas.

• So, pV = nRT.

• Or, V = $\frac{nRT} {p}$

• So, it is actually corresponding to the equation of the straight line
• y=mx+c.

• Here y is the V and x is the T.

• The constant is 0 and the slope of the graph is $\frac{nR} {p}.$

• So, the slope is inversely proportional to the pressure of the gas.

• So as the volume increase, the pressure will decrease at a constant temperature.

• So as V1>V2>V3>V4,

• So P₁ < P₂ < P₃ < P₄
