Question

Pressure versus temperature graph of an ideal gas of equal number of moles of different volumes are plotted as shown in figure. Choose the correct alternative

(a) V₁ = V_2, V₃ = V₄ and V₂ > V₃

(b) V₁ = V₂, V₃ = V₄ and V₂ < V₃

(c) V₁ = V₂ = V₃ = V₄

(d) V₄ > V₃ > V₂ > V₁

Answer 1

Correct Option (a) V₁ = V_2, V₃ = V₄ and V₂ > V₃

Explanation:

 

It means line of smaller slope represent greater volume of gas. For the given problem figure

Point 1 and 2 are on the same line so they will represent same volume i.e. V₁ = V₂

Similarly point 3 and 4 are on the same line so they will represent same volume i.e. V₃ =V₄

But V₁ > V₃ (= V₄ ) or V₂ > V₃ (= V₄ ) as slope of line 1-2 is less than 3-4.
