Question

A partition divides a container having insulated walls into two compartments I and II. The same gas fills the two compartments (shown in figure). The ratio of the number of molecules in compartments I and II is–

• A. (a) 1 : 6
• B. 6 : 1
• C. 4 : 1
• D. 1 : 4

Answer 1

Answer: (B)

6 : 1

Answer 2

v_rms µ $\sqrt{T}$ [T = temperature in Kelvin]

T₁ = 27 + 273 = 300 K

T₂ = 4 × 27 + 273 = 381 K

\ v₂ = $\sqrt{\frac{381}{300}}$× 500 ${}_{–}^{\sim}$ 560 m/s
